# How to Calculate the Date Difference in Excel

There are several ways to calculate dates in Excel. For example, you can add or subtract days from a day using the DATEDIF function. If you want to find out how many days are left before a date, you can use a day calculator. But what about subtracting years? If so, how do you use this function? In this article, we’ll discuss two methods. Using the DATEDIF function:

## Adding or subtracting days from a date

These calculators allow you to input the date to be added or subtracted from and display the result in days. For example, if you want to subtract 90 days from Feb. 20, 2019, you will get Nov. 22, 2018. You can also use these calculators to convert time intervals between weeks, months, years, and even decades. Although weeks have a fixed length of seven days, the other time measures have variable lengths, so the exact number of days will vary.

In most cases, people need to add days before marking their calendar. For instance, payment notices may be due in 14 days from the date of issuance. In these cases, people need to add days before marking calendars. There are also cases where they need to subtract days from dates for the same purpose. For example, you may want to know how many days will remain 날짜계산기 after a certain date without the weekend.

## Adding or subtracting years from a date

The easiest way to add or subtract years from a day is to use the EDATE Function. This function adds a specified number of months to a date, and you can add years by multiplying the months by twelve. Another option is to use the DATE Function, which creates a day using a given year, month, and day. You can add years in any other way you see fit.

Excel treats dates as numbers and stores them as 40826. Adding years is almost impossible to do with Excel, so there is a “Date” function that makes it possible to perform this operation. This function targets the year in calculations and displays it in either day or month format. However, if you’re calculating dates thousands of years ahead, you should use the ‘Year’ function instead.

## Using the DATEDIF function

The DATEDIF function calculates the difference between two dates. It accepts two arguments: start_day and end_day . The start_date must be greater than the end_date or a #NUM error will occur. Alternatively, you can specify the days and years of interest. In this case, the DATEDIF function will return the difference as a number. The DATEDIF function is particularly useful when you need to know the age of a person.

The DATEDIF function works by calculating the time between two dates. It takes an input string and two parameters (start_date and end_date). You can specify a date as an array, as long as you include the time units. This function can be used to calculate the number of days or months between two dates. But it will give you unexpected results if the second day has a lower day/month number than the first.
