# How to Subtract Date and Time in Excel?

We all know that Excel can be a great tool for managing data and generating reports. But did you know that you can use it to subtract date and time too? This can be a handy tool for tracking project deadlines, calculating payroll, and more. In this article, we’ll walk you through the steps of how to subtract date and time in Excel, from setting up the formulas to troubleshooting any issues. So, if you’re ready to get started, let’s go!

## How to Subtract Date and Time in Excel

Subtracting dates and times in Excel is an easy task. It can be useful for keeping track of time, calculating project deadlines, and working with meeting schedules. In this tutorial, we’ll show you how to subtract dates and times in Excel and provide some helpful tips for getting the most out of your calculations.

The most basic way to subtract dates and times in Excel is to use the “-” operator. This operator will subtract one date and/or time from another, resulting in the number of days, months, or years that have passed since the first date value. For example, if you enter “=3/15/2021-3/1/2021” into an Excel cell, the result will be “14 days”. Similarly, you can use the operator to subtract two times, such as “=7:00 PM-5:00 PM”, which will result in “2 hours”.

### Using Excel’s Date and Time Functions

In addition to using the “-” operator, Excel also provides several built-in functions that make subtracting dates and times easier. The most commonly used function is the DATEDIF function, which can be used to calculate the number of days, months, or years between two dates. For example, if you enter “=DATEDIF(3/1/2021,3/15/2021,”d”)” into an Excel cell, the result will be “14 days”.

Another useful function for subtracting dates and times is the NETWORKDAYS function. This function can be used to calculate the number of working days between two dates, excluding weekends and holidays. For example, if you enter “=NETWORKDAYS(3/1/2021,3/15/2021)” into an Excel cell, the result will be “10 days”.

### Calculating Date Differences Automatically

Excel also provides a feature that allows you to automatically calculate the difference between two dates and times. To use this feature, simply select both date and/or time cells, right-click the selection, and select the “Calculate Date Difference” option. This will display a dialog box where you can select the units of measurement (days, months, or years) and the calculation type (duration or elapsed time).

### Formatting Date and Time Cells

When working with dates and times in Excel, it is important to properly format the cells. To do this, select the cells that contain the dates and/or times, right-click the selection, and select the “Format Cells” option. This will open the Format Cells dialog box, where you can select from a variety of date and time formats.

### Tips for Working with Dates and Times in Excel

When working with dates and times in Excel, here are a few tips to keep in mind:

#### Use the Shortcut Keys

Excel provides several shortcut keys for working with dates and times. For example, pressing “Ctrl+;” will insert the current date into a cell, and pressing “Ctrl+Shift+:” will insert the current time.

#### Be Aware of Time Zones

When working with dates and times, it is important to be aware of time zone differences. To ensure accuracy, make sure that all dates and times are in the same time zone.

#### Use the DATEVALUE Function

If you need to convert a text string into a date, you can use the DATEVALUE function. This function takes a text string (such as “March 15, 2021”) and converts it into a date value.

#### Use the NOW Function

The NOW function can be used to insert the current date and time into a cell. This can be useful for keeping track of when a certain action was performed or when a file was last updated.
