How many weeks from date to. Calculating date difference in Microsoft Excel

Calculation of working days and weekends

The calculator is quite simple, but nevertheless, in my opinion, it is very convenient for calculating the number of working days between arbitrary dates.

The calculator uses data on the postponement of working days and holidays, which are contained in the annual decrees of the Government of the Russian Federation.

Of course, there are many such calculators and we are not original in this, but there are a few highlights that I think you will like, and can be used to create other calculators.

The first highlight: We may not take into account the holidays that are contained in the decrees of the Government of the Russian Federation, but take into account only weekends (for Russia, Saturday and Sunday)

The second highlight: For those countries that have weekends on other days of the week (for example, in Israel, weekends are Friday and Saturday), you can specify which days of the week will be days off. This is convenient not only for other countries, but also for local application, when it is known that we work in shifts, every Thursday, Saturday and Tuesday.

The third highlight: We can use a completely arbitrary weekend system, set in a certain form (this function is not displayed on the site, although the functionality is working) and for everyone, build production calendar for Belarus, Kazakhstan or Serbia will not be difficult.

A pleasant side effect of this calculator is also the calculation of the number of days between two dates. Moreover, she calculates the difference as it is done in the accounting department and the personnel department. That is, if a person works from July 1 to July 8, then it turns out 8 days. Since the last day is considered a working day.

Unlike mathematical and astronomical calculators, where the same data gives 7 days. This error appears in one day due to the fact that in personnel decisions the last day, he is always a worker and must be taken into account, and in precise and abstract calculators it is believed that July 8 comes at midnight (0: 0: 0) and the difference between midnight on July 1 and midnight on July 8 (or 23 hours 59 minutes 59 seconds 999 milliseconds, 999999 microseconds, etc. on July 7) will be exactly 7 days.

The main principle followed by the bot is the frequency of weekends. If this is the case, the calculator will return the result you expected.

It is a pity that in the decrees of the Government of the Russian Federation they still do not implement a QR code, where all holidays for the current code would be indicated for machine processing. This would simplify the work of a certain circle of people.

Holidays and transfers on the territory of the Russian Federation are taken into account from 2010 to 2019 inclusive.

For users who need to calculate the first working date after a vacation or business trip or other period of time, pay attention to this calculator Date of leaving work from vacation, decree online

rab_d start date; date.end; week

a week - gives complete information on how to calculate working days and hours. The week consists of seven characters 0 or 1, where each character has its own role. 0 - a person works, 1 - a person does not work (day off). If the week is empty, then the code 0000011 is used - that is, Saturday and Sunday are days off.

I would like to note that this calendar week and this indicator shows how you rest during the week. The week numbering for us starts from zero and this day is Monday, then comes Tuesday -1, Wednesday-2, etc.

the date of the beginning - date in the form of DD / MM / YYYY - denotes the beginning of the range for which the number of working days is calculated

end date - date in the form of DD / MM / YYYY - denotes the end of the range for which the number of working days is calculated

ATTENTION! The date can be entered with a period or a slash. It is more convenient to enter through a dot on cell phones and tablets, and through a slash it is more convenient on a computer on the keyboard on the right (numeric panel)

Examples of using

rab_d 1/1/2014; 31/12/2014

in response we will receive

Number of days between two specified dates 365

Number of working days 247

Number of weekends and holidays 118

rab_d 2/7/2010; 10/25/2013

In response, we get

Number of days between two specified dates 1212

Number of working days 827

Number of weekends and holidays 385

rab_d 20/1/2010; 10/2/2014; 0101001

In response, we get

Number of days between two specified dates 1483

Number of working days 797

Number of weekends and holidays 686

For the previous example, just ignore public holidays. As an option for use, shift duty, security, etc.

Apparently this is a very common phenomenon. Immediately went to the Internet to search online service, which allows calculate how old a person is by their date of birth.

As expected, there are such services. And not a little. Talented PHP programmers have taken care of "Lost in time" and wrote all sorts of calculator scripts for counting years by date of birth, or simply calculating the number of years, months, days, hours, minutes and even seconds between two dates online.

I also want to write about some of them.

Calculation of how many years, months, days, hours, minutes have passed by date of birth

Surely many wondered: "How many days have I lived?" ... But not many bothered to count. This is a very tedious task. But with the help of this site:

you can easily calculate by date of birth... You will find out how old you are, months, days, hours, minutes, seconds and even milliseconds.

The service will also give you the time after which your next birthday will be.

Count days and years between two dates - online calculator

http://planetcalc.ru/274/ - with the help of this calculator you will be able to count days and years between two dates in online mode. Just enter the required data and the service will give you an accurate result.

Counting the number of days from date to date

http://www.calculator888.ru/skolko-dnei/ is another site where you can find out exactly how old a person is. Moreover, on it you can calculate online the number of years, months, days, hours, minutes, seconds elapsed from one date to another.

To perform certain tasks in Excel, you need to determine how many days have passed between certain dates. Fortunately, the program has tools that can solve this issue. Let's find out in what ways you can calculate the difference in dates in Excel.

Before you start working with dates, you need to format the cells for this format. In most cases, when you enter a character set similar to a date, the cell will reformat itself. But it's better to do it manually, to insure yourself against surprises.

Now all the data that will be contained in the selected cells, the program will recognize as a date.

Method 1: simple calculation

The easiest way to calculate the difference in days between dates is using a regular formula.

Method 2: DATED function

To calculate the difference in dates, you can also use the special function DATEDATE... The problem is that it is not in the list of the Function Wizard, so you will have to enter the formula manually. Its syntax is as follows:

DATEDATE (start_date, end_date, unit)

"Unit"- this is the format in which the result will be displayed in the selected cell. The unit in which the total will be returned depends on what character will be substituted into this parameter:

• "Y" - full years;
• "M" - full months;
• "D" - days;
• "YM" is the difference in months;
• "MD" is the difference in days (months and years are not counted);
• "YD" is the difference in days (years are not counted).

You also need to note that, unlike the method using the simple formula described above, when using this function, the start date should be in the first place, and the end date should be in the second. Otherwise, the calculations will be incorrect.

Method 3: calculating the number of business days

Excel also has the ability to calculate working days between two dates, that is, excluding weekends and holidays. To do this, use the function CLEANER... Unlike the previous operator, it is listed in the Function Wizard. The syntax for this function is as follows:

NETWORKDAYS (start_date; end_date; [holidays])

In this function, the main arguments are the same as for the operator DATEDATE- start and end date. In addition, there is an optional argument "Holidays".

It should be replaced by the dates of public holidays, if any, for the period covered. The function calculates all days of the specified range, excluding Saturdays, Sundays, as well as those days that are added by the user to the argument "Holidays".

After the above manipulations, the number of working days for the specified period will be displayed in the pre-selected cell.

As you can see, the Excel program provides its user with a fairly convenient toolkit for calculating the number of days between two dates. At the same time, if you just need to calculate the difference in days, then a more optimal option would be to use a simple subtraction formula, and not use the function DATEDATE... But if you need, for example, to count the number of working days, then the function will come to the rescue CLEANING DAYS... That is, as always, the user should decide on the execution tool after he has set a specific task.

Free online calculator Contour. Accounting will help you and tell you how many days have passed between two specified dates. In addition, if you have a need, you can calculate how many calendar, days off or working days (hours) the specified period of a year or several years contains.

How many days are there between dates? Instructions

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

Important: you cannot take the indicators of working days / hours per month from the calculations for previous years and provide them as calculations - the data will differ. Therefore, it is better to use a calculator.

So, the order of actions:

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 2018.
2. Set in the next field the number of working hours per day. 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, on the banner, you will see the result obtained: working days, calendar days and working hours between the given dates. The results must be copied and saved in your document.

What you can use the calculator for

1. For calculating penalties and delinquencies under contracts
2. How to understand the efficiency of using a resource and the deadlines for use
3. How not to accidentally schedule a task for a weekend
4. How much time is left until the deadline

Example:

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

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