Subtracting hours and minutes. Adding time in Microsoft Excel

Instructions

If this is your first time encountering a time calculation task, try not to immediately resort to complex functions. Most calculations can be done simply mathematical formulas: addition and subtraction. And be sure to format the cells correctly.

To do this, select the range of cells into which data will be entered and right-click on the selection, or open the “Home” tab and click the “Format” button in the “Cells” tool block. In both the first and second cases, select the “Format Cells” item in the context menu.

A new dialog box will open, make sure you are on the Number tab. In the list located on the left side of the window, select the “Time” item with the left mouse button. In the right part of the window, indicate in what form it should be presented. time. Click on the OK button to confirm your choice.

Enter data into the cells in the format XX:XX (or XX:XX:XX). To calculate the time interval between the first and second value, place the cursor in the cell where the total value appears. In the formula bar, put an equal sign, left-click on the cell with the last value, enter a minus sign, then click on the cell with the first value. Press Enter.

For example: the period of time elapsed from 11:10:15 to 12:30:00 is 1 hour, 19 minutes and 45 seconds. The total value in cell C2 is calculated using the formula: =B2-A2. If you need to calculate a period of time in multiple rows (A3 and B3, A4 and B4, and so on), simply drag the AutoFill marker from cell C2 to the end of your table column (C3, C4).

If you need to calculate the total number of hours, minutes and seconds it took to do something, simply add up the data obtained as described above using the SUM function. Place the cursor in the cell with the total value, click on the fx button, in the window that appears, select the SUM function with the left mouse button and mark the range of cells that will participate in the calculation. Press Enter. The formula for calculating will look like this: =SUM(C2:C4).

Microsoft Excel- a powerful tool for working with tables, providing almost limitless possibilities for collecting and analyzing all kinds of data, constructing charts, and creating reports. However, you can also use it as a regular calculator.

1. In any, enter =2+2. The result of the calculation will appear in the cell - the number 4. Please note that if you simply write 2+2, then this exact text will be visible. In order for Excel to understand that the user wants to perform operations, and not just write them down, it is necessary to precede the formula with an = sign.


2. The rules for performing calculations in Excel are the same as in regular school arithmetic. For example, the results of calculating =(5+5)*2 and =5+5*2 will be completely different. Use parentheses to determine the order of calculations you need.


3. Ability to count from using excel would not be so useful if the program did not allow the contents of . Enter 10 in any number, 2 in any other cell. Enter the = sign in another cell, then left-click on the first cell, enter the - sign and left-click on the second cell. A similar to =I9-G8 will appear, and after pressing Enter you will see the result of the subtraction - the number 8. Try entering other numbers in the first two - you will see that the value in the third changes automatically, immediately after adjusting the data in the first cells.


4. Excel has formulas that allow you to process entire arrays of cells. Select several cells arranged in a vertical column and enter any numbers in them. Place the cursor on the cell below the bottom cell with the number. Type =sum(then highlight the numbers with the mouse. Type the closing parenthesis and press Enter. As a result, a number equal to their sum will appear under the column. Excel has many more complex ones that allow you to perform a variety of complex mathematical, statistical and other calculations.

A calendar is a way of counting and displaying large periods of time.
All our calculations are carried out within the framework of the Gregorian calendar, which is now generally accepted throughout the world (the average length of the year is 365.2425 days). When making historical calculations, please check the dating. The difference between the Gregorian and Julian calendars is now 13 days, but early centuries the number of days between equal dates was smaller, the smaller the closer to the beginning of our era ().

Here is a simple online calculator, aware of its, alas, modest capabilities, and not an astronomical program!

Please enter a different number.

Based on this small scoreboard, it was created.

Now the calculation table is configured to count the days until the start of summer.

To calculate how many days have passed or will pass between the dates you are interested in, simply enter them in the appropriate fields of the table. The time interval can be changed in the same way as dates, in this case the countdown will be from “Date 1”, and “Date 2” will change.
The calculation results also display unchangeable information values ​​and indicators - these are the days of the week (dark gray - weekdays, orange-red - weekends) and, as a final summary, the interval between dates, expressed in years, months, days, hours and minutes .

If on the scoreboard you see the most fateful period in history for our country - the days between the dates of the Great Patriotic War, then it means that Jawa Script is disabled in your browser and you need to enable it to perform calculations.

* Within 2019 of the year calculation of working days is underway taking into account Russian holidays and the scheme for transferring weekends approved by the government of the Russian Federation. At large intervals time between dates, calculations of the number of working days are carried out on the assumption of a five-day working week, Holidays are not taken into account.

Reference: It is reliably known that at the end of the first millennium in Ancient Rus' Time was counted according to the Julian calendar, although New Year celebrated on March 1, counting time according to this calendar is called March style. The difference between the equal dates of the modern and ancient calendars on March 1, 1000 was 59+6=65 days (6 days difference between the Julian and Gregorian calendars; dates with equal numbers and equal month numbers from the beginning of the year are considered equal dates).
In 1492, by resolution of the Moscow Council of the Russian Orthodox Church a calendar was adopted according to which the new year (New Year) began on September 1 ( September style ), the difference with the modern calendar was 9-122=-113 days.
Two centuries later, on the eve of the round calendar date Peter the Great introduces a calendar that calculates from the Nativity of Christ. New Year in Russia has been celebrated on January 1 since 1700 (though, in fact, according to modern calendar this new year came on January 11, 1700). The country went from 7208 to 1700! So, in the then new 18th century, which began in 1701, Russia entered almost in step with Europe. Almost in step, because chronology, as before, was carried out according to the Julian calendar (only the dating has changed, now it is called old style) , while Europe has already partially switched to Gregorian calendar.
The modern Gregorian calendar in Russia was adopted only in the 21st century. January 26, 1918: Vladimir Ilyich Lenin signed a decree of the Council of People's Commissars on the transition to a new calculation of time, while the dating shifted by 13 days. The last state document dated according to the old style was published on January 31, 1918 - the next day was February 14!
So the question is: "How many days are there between two dates?" in a historical sense always requires clarification...

The free online calculator Kontur.Accounting will help you and tell you how many days have passed between two given dates. In addition, if you have a need, you can count how many calendar, weekend or working days (hours) it contains specified period year or several years.

How many days are there between dates? Instructions

You simply set a specific start and end day and get a quote in a split second. The online calculator calculates all data independently. If you change the original days of the week, the result is automatically recalculated to take into account leap years.

Important: you cannot take monthly working days/hours from last year’s calculations and provide them as calculations - the data will vary. Therefore, it is better to use a calculator.

So, the procedure is:

1. In the “Start date” and “End date” fields, select the start and end day of the countdown, respectively, starting from 2013 and ending in the future in 2018.
2. Set the number of working hours in a day in the next field. By default, this field is already set to 8 hours (40-hour work week), but you can change this number.
3. On the right side of the screen in the banner you will see the result: working days, calendar days and working hours between the specified dates. The results must be copied and saved in your document.

What can you use a calculator for?

1. To calculate penalties and delays under contracts
2. How to understand the efficiency of using a resource and the deadlines for use
3. How to avoid accidentally scheduling tasks on a weekend
4. How much time is left until the deadline

Example:

You are an accountant. The manager has asked you in the next couple of minutes to provide data on the number of working hours that all company employees must work in February. You can easily determine the number of employees - you have the numbers in front of your eyes. But the number of hours needs to be counted.... How many days are there in February? Is it a leap year? What days were weekends? How to determine the number of days of holidays?

Solution: just use our widget. You will receive all the information automatically; you do not need desktop calendars and calculators.

Time calculator

Time calculators — software, designed for calculations using numbers in time format.

Typically, a time calculator allows you to perform the following procedures:

Adding and subtracting values ​​in time format (example: 2.15 + 2.50 = 5.05);

multiply the time (in hours and minutes) and the rate (in boxes and clips) to calculate the total costs (example: 3.05 * 8050.30 = 24794.92) or vice versa, the rate is multiplied by the time;

divide the amount (in boxes) by the tariff (in boxes) and find the time (in hours and minutes), (example: 300000 / 8050.30 = 37.16);

divide the quantity (in boxes) by time (in hours and minutes) and get the tariff (in boxes) (example: 300000 / 20.50 = 37.16);

Divide the fuel consumption (in liters) by the time (in hours and minutes) and get the hourly flow (L) (example: 3L / 0.30’ = 0.6 l/h)

Most modern time calculators typically have two modes of operation:

gradual rounding (we accept this on most sections account in combination with manual calculation methods).

Example: 3.05 (3 hours 5 minutes) * 1000 p = 3080 rub. First 5/60 = 0.0833333. The value is rounded to 0.08. Therefore, the time at the tenth hour is 3.08 times 1000p = 3080r.

only rounds final result. Example: 3.05 (3 hours 5 minutes) * 1000 p = 3083.33 rubles.

First 5/60 = 0.0833333. Therefore, the time of the tenth hour is 3.0833333 times 1000p = 3083r 33 k.

Before calculating the standard working time, you need to decide on the billing period. The most difficult thing is to make calculations for the year, since you need to take everything into account public holidays and postponing holidays. And if employees work on a shift schedule, then in addition to the norm, the number of overtime hours must be determined.

general information

Information on working hours is contained in Article 91 of the Labor Code of the Russian Federation. This period refers to the period of time when a person performs labor functions. By law, the standard duration of this time is 40 hours per week. In practice, such working hours are rarely used.

Firstly, in many enterprises manufacturing process it is impossible to stop, so the work schedule there is shifting. Secondly, some categories of employees cannot work for such an amount of time, since by law they are entitled to a reduction in labor standards. These are minors, people with disabilities, etc.

However, the rules for calculating working hours stipulate that a 40-hour working week should be taken as a basis.

Calculation for a month

Determining labor standards allows employers to correctly set work schedules, keep records of hours worked, and pay wages and distribute vacations. Knowing how to correctly calculate the standard working time, you can easily determine how many hours an employee must work. One calendar month is often taken as the billing period.

Working hours are calculated as follows:

1. First you need to find out how many working days there are in the selected accounting period, and how many weekends, holidays, etc.
2. Next, the number is calculated working hours in a day. At the same time, do not forget that the normal length of a working week is 40 hours. This means you calculate the number of hours per working day. Example: 40/5=8.
3. The number of days in a month when a subordinate works must be multiplied by 8 hours.

An example of such a calculation could be as follows:

1. Let's say there are 21 working days in June.
2. The authorized employee must determine the standards by which the personnel will work.
3. For this, the time standard will be calculated using the following formula: 21*8=168 hours. This is exactly how much each subordinate must work on average.

Quarterly calculation

It is also important to know how to calculate the standard working hours for a quarter, that is, for three months. The standard working day is 8 hours. All calculations are carried out very simply. First you need to determine what the labor norm is in each month.

Calculation example:

1. Let's assume that there are 168 work hours in July. It remains to calculate the amount of time only for the next 2 months.
2. There are also 168 working hours in August, and 160 in September.
3. This means that the norm for the quarter is as follows: 168+160+168=496 hours.

If necessary, a similar calculation can be carried out for each quarter. Most often, company management uses the definition of the norm on a quarterly basis.

Calculation for a year

Labor rationing is an important procedure that allows you to determine the number of hours that employees are required to work. When making calculations, the calendar year is often used as the accounting period. Hours are calculated in two ways. You can use the method that is used to calculate the quarter. You just need to determine the amount of the working period for all 12 months.

Another procedure for determining the norm was established by order of the Ministry of Health and Social Development of the Russian Federation No. 588n. The calculation is carried out using the formula: 40/5*number of working days per year. After this, from the resulting number you should subtract the number of hours that the employees did not work. It's about about reduction before holidays.

When determining the norm for 2019 according to the billing period, the following nuances should be taken into account:

1. Sunday must be counted as a day off. And it doesn’t matter how many days of rest a subordinate actually has per week - 2 or 1. For some categories of subordinates, it is possible to transfer the day of rest to another date.
2. Don't forget about official holidays, which are not used in calculations.
3. When a holiday falls on a day of rest, the day off is postponed. These rules do not need to be used only when calculating labor standards for January.
4. Duration working day before a holiday it is always reduced by 1 hour.

When making calculations, you must follow these rules, otherwise the final number of hours will be incorrect.

Shift work

When determining standards, the standard number of days of labor per week is used. But not all employers can afford such a working regime. Therefore, the standard working time shift schedule you have to calculate a little differently. This is the so-called summation, when the total number of hours worked is determined.

But their number during the accounting period should not exceed the established norm. That is, all hours that were worked in excess of the norm are additional or overtime. As an example, you can use the following data: in a calendar month, the employee worked 175 hours against the norm of 160 hours. Therefore, 15 of them are counted as additional.

Summarized accounting at an enterprise is established according to the following rules:

1. The duration of the billing period is determined. The standard ones are used - month, quarter, year.
2. A specific schedule is established according to which the employee works.

The accounting period can be anything in length, but not more than one calendar year. There are special restrictions that prevent you from installing a large number of overtime hours. For example, there cannot be a 4-hour overtime for 2 days in a row. And per year - no more than 120 hours.

Cumulative accounting implies that wages are paid based on hours worked. Most often, different tariffs are used. Example: hourly rate persons – 100 rubles. This means that for a 10-hour shift he receives 1 thousand rubles. If we take into account that he works 50 hours a week, then his earnings will be 5 thousand rubles.

Types of charts

The length of the working day most often depends on production needs. Therefore, it is rare that employers can provide their staff with a standard 5-day period. The most commonly used modes are:

1. 24 hour shift with several days off.
2. Work shift with 10 or 12 hours of work. Then the staff has more days off than planned.
3. Shift is 12 hours, with alternating day and night shifts.

Note: these are not all the regimes that able-bodied citizens have to face. But, based on the specifics of some professions, a regular 8-hour shift may be disadvantageous for both management and the subordinates themselves.

Production calendar

In order for managers to correctly calculate labor standards, there is a special document. This is the so-called production calendar, which takes into account all working days, as well as rest days, including holidays. This document is not normative act, therefore has no legal force.
