# What is the Formula to Calculate the Number of Days Between Two Dates in Excel?

If you need to know the number of days between two dates in Excel, there are a few simple methods you can use. One of them is the DATEDIF function, which is a little more advanced but can help you find out the difference between dates in terms of days, months or years.

The DATEDIF function is not a standard Excel function, so you’ll have to type it manually into your formula bar or worksheet. It accepts three arguments: start date, end date and unit. The first argument is the unit you want to measure in, and the second argument is the difference between the two dates. The third argument can be “D”, “M” or “Y” for days, months or years respectively.

#### DAYS (function)

The Excel DAYS function is one of the most popular ways to calculate the number of days between two dates. This function can be used for many different purposes, but it is particularly useful when you need to work out the number of working or non-working days between two dates. It can also be used to calculate the total number of days between two dates, which is especially important if you are doing any kind of Gantt chart or timeline in Excel.

This function works well in most cases, but it can be a little trickier if you have a lot of dates and want to exclude certain holidays from the calculation. You can do this by entering a list of dates that you would like to exclude from the count, or you could enter them as references to cells in your spreadsheet.

#### NETWORKDAYS (function)

This Excel function is another great option to calculate the number of business or working days between two dates. It can be used for any purpose where you need to work out the number of business days between two dates and include or exclude holidays.

Using the NETWORKDAYS function is easy, but it can get tricky if you need to include a list of holidays from the calculation. The quickest way to do this is to add the holiday dates to additional cells in your spreadsheet, then press the Holidays cell reference button on the NETWORKDAYS function window to select those cells.

#### Leap Year Considerations

If you’re expecting a baby, or are looking to work out the number of days until your next birthday, it is important to keep in mind that leap years can affect the number of days between your dates. This can cause a lot of confusion, but it isn’t impossible to figure out if you’re going to have a leap year and be prepared.

In most countries, there are a minimum of 26 working days between two dates. This can be important for any contract you may be negotiating or if you’re offering to perform a task in a specific amount of time in the future.

This Excel function can be a little tricky if you have a lot of dates or are trying to work out the number of days between two dates, but it is well worth giving it a try. It is a simple to use formula and can be very helpful when you need to work out the number of days between dates.
