Apparently this is a very common occurrence. Immediately got on the Internet to look for an online service that allows calculate how old a person is by his date of birth.

As expected, such services exist. And not a few. Talented PHP programmers took care of "lost in time" and wrote all kinds of calculator scripts to calculate years by date of birth, or just calculate the number of years, months, days, hours, minutes and even seconds between two dates online.

I would like to write about some of them.

How many days between dates? Instruction

You simply set a specific start and end day and get a calculation in a fraction of a 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 the leap year.

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

So, the procedure is:

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

What can you use the calculator for?

To calculate penalties and delays under contracts
How to understand the efficiency of using a resource and the deadlines for using it
How not to accidentally schedule a task on a weekend
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? What about a leap year? What days were the days off? And 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.

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 now generally accepted throughout the world (the average length of a year is 365.2425 days). When making historical calculations, please check the dates. The difference between the indications of the Gregorian and Julian calendar is now 13 days, but in the early centuries the number of days between equal dates was less, the less, the closer to the beginning of our era ().

Sorry!

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

Please enter another number.

Based on this small scoreboard created.

Now the calculation table is configured to count the days until the beginning 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, while the countdown will be from "Date 1", and "Date 2" will change.
The calculation results also display unchanging 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 of history for our country - the days between the dates of the Great Patriotic War, then it means that Java Script is disabled in your browser and must be enabled for calculations.

* Within 2019 of the year working days calculation ongoing taking into account the holidays of Russia and approved by the government of the Russian Federation scheme for the transfer of days off. For long periods of time between dates, the calculation of the number of working days is based on the assumption of a five-day working week, holidays are not taken into account.

Reference: It is authentically known that at the end of the first millennium in Ancient Russia, the time was counted according to the Julian calendar, although the new year was celebrated on March 1, the countdown according to such a calendar is called the March style. The difference between equal dates of the modern and ancient calendar on March 1, 1000 was 59 + 6 = 65 days (6 days difference between the readings of the Julian and the Gregorian calendar, equal dates are considered dates with equal numbers and equal numbers of months from the beginning of the year).
In 1492, by a decree of the Moscow Cathedral 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 leading from the Nativity of Christ. The New Year in Russia is celebrated on January 1 from the beginning of 1700 (although, in fact, according to the modern calendar, this new year came on January 11, 1700). The country moved from 7208 to 1700! So, in the then new 18th century, which came in 1701, Russia entered almost in step with Europe. Almost in step, because the chronology, as before, was conducted according to the Julian calendar (only the date has changed, now it is called old style) , while Europe has already partially switched to the 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 time calculation, while the dating shifted by 13 days. The last state document dated according to the old style was issued 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 ...

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 how you can calculate the date difference 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 that looks like a date, the cell will reformat itself. But it is still better to do it manually to insure yourself against surprises.

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

Method 1: simple calculation

The easiest way to calculate the difference of days between dates is with a simple formula.

Method 2: RAZDAT function

You can also use a special function to calculate the difference in dates RAZDAT. The problem is that it is not in the list of the Function Wizard, so you have to enter the formula manually. Its syntax looks like this:

RAZDAT(start_date, end_date, unit)

"Unit"- this is the format in which the result will be displayed in the selected cell. The symbol used in this parameter determines the units in which the total will be returned:

"y" - full years;
"m" - complete months;
"d" - days;
"YM" - difference in months;
"MD" - the difference in days (months and years are not taken into account);
"YD" - the difference in days (years are not taken into account).

You also need to note that, unlike the simple formula method described above, when using this function, the start date must 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 working days

Excel also has the ability to calculate the working days between two dates, that is, excluding weekends and holidays. For this, the function is used CHISTRABNI. Unlike the previous statement, it is listed in the Function Wizard. The syntax for this function is:

NETWORKDAYS(start_date, end_date, [holidays])

In this function, the main arguments are the same as those of the operator RAZDAT- 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, and also 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 users with a fairly convenient tool for calculating the number of days between two dates. At the same time, if you just need to calculate the difference in days, then the best option would be to use a simple subtraction formula, rather than using the function RAZDAT. But if you need, for example, to calculate the number of working days, then the function will come to the rescue NETWORKDAYS. That is, as always, the user should decide on the execution tool after he has set a specific task.

The date calculator is designed to calculate the number of days between dates, as well as to find a date by adding or subtracting a certain number of days to a known date.

Add days to a date

In order to find out what date will be in a certain number of days, use this option. Enter the start date and the number of days to add to it. To subtract, use the minus value. The calculator also has an option to add business days only.

Calculating the number of days between dates

This calculation method will answer the question "how many days have passed since the date". Enter the start date and end date and click the "calculate" button. The calculator will show how many days between the entered dates. Separately, the calculator will show the number of working days.

With this option, you can calculate how many days are left until a certain event, such as a birthday or a holiday. To do this, enter today's date in the start date field, and the date of the event in the end date field.

Holidays

The calculator can calculate, add and subtract both calendar days and working days. Official non-working holidays are:

January 1,2,3,4,5,6,8 - New Year holidays
January 7 - Orthodox Christmas
February 23 - Defender of the Fatherland Day
March 8 - International Women's Day
May 1 - Spring and Labor Day
May 9 - Victory Day
June 12 - Day of Russia
November 4 - National Unity Day

If a public holiday falls on a Saturday or Sunday, it is moved to the next business day. But sometimes the weekend is moved to a completely different place on the calendar. For example, Saturdays and Sundays that fall on New Year's holidays can be moved to May to extend the May holidays.

So, in 2019 the situation is as follows...

Postponement of holidays in 2019

In addition to official holidays, in 2019, May 2, 3 and 10 are also days off due to the transfer of days off from the New Year holidays.

When calculating days, our calculator takes into account both official holidays and all transfers.
