Knowing how to subtract date and time in Excel can be a useful skill for anyone who works with spreadsheets. In this article, we’ll show you exactly how to do it. We’ll walk you through the steps you need to take to subtract two dates, two times, or a date and a time in Excel. With our simple instructions, you’ll have the knowledge you need to accurately calculate the time difference between two dates and times in no time!

**Subtracting Date and Time in Excel**

Subtracting date and time in Excel is easy. To do so, simply subtract the two dates using the minus sign (-) operator. The result will be the difference between the two dates in days. For example, to subtract the date 01/01/2020 from 01/02/2020, simply enter =01/02/2020-01/01/2020 into a cell.

If you need to subtract time as well, then you will need to use the DATEDIF function. To calculate the difference between two times, simply enter =DATEDIF(start_time, end_time, “h”) into a cell, where start_time and end_time are the two times you want to subtract. This will return the difference between the two times in hours.

## Understanding the Format for Date and Time

Subtracting dates and times in Microsoft Excel requires a basic understanding of the format Excel stores date and time values. In Excel, dates are stored as a number representing the number of days since 1/1/1900. Similarly, times are stored as a number representing the number of seconds since midnight.

To subtract dates and times, Excel needs to be able to recognize that the values are in the correct format. For example, a date needs to be formatted as a date, and a time needs to be formatted as a time. If the values are not properly formatted, then the subtraction will not work correctly.

Once the values are properly formatted, Excel can subtract the values to calculate the difference between the two dates or times. For example, if you have two cells that contain dates, Excel can subtract the dates to calculate the number of days between the two dates. Similarly, if you have two cells that contain times, Excel can subtract the times to calculate the number of hours, minutes, or seconds between the two times.

## Subtracting Dates and Times in Excel

To subtract dates and times in Excel, use the subtraction operator (-). For example, if cell A1 contains the date “1/1/2021” and cell B1 contains the date “1/1/2020”, then you can subtract the two cells to calculate the difference in days between the two dates. The formula to do this is =A1-B1.

If cell A1 contains the time “12:00 PM” and cell B1 contains the time “11:00 AM”, then you can subtract the two cells to calculate the difference in hours between the two times. The formula to do this is =A1-B1.

### Subtracting Dates With Different Formats

If you have two dates with different formats, then you need to convert the formats to the same format first before subtracting the dates. For example, if cell A1 contains the date “1/1/2021” in the mm/dd/yyyy format, and cell B1 contains the date “January 1, 2021″ in the mmmm dd, yyyy format, then you need to convert the formats to the same format before subtracting the dates.

To do this, you can use the TEXT function to convert the date in cell B1 to the same format as the date in cell A1. The formula to do this is =TEXT(B1,”mm/dd/yyyy”). Then, you can subtract the two cells to calculate the difference in days between the two dates. The formula to do this is =A1-TEXT(B1,”mm/dd/yyyy”).

### Subtracting Times With Different Formats

If you have two times with different formats, then you need to convert the formats to the same format first before subtracting the times. For example, if cell A1 contains the time “12:00 PM” in the h:mm AM/PM format, and cell B1 contains the time “12:00″ in the hh:mm format, then you need to convert the formats to the same format before subtracting the times.

To do this, you can use the TEXT function to convert the time in cell B1 to the same format as the time in cell A1. The formula to do this is =TEXT(B1,”h:mm AM/PM”). Then, you can subtract the two cells to calculate the difference in hours between the two times. The formula to do this is =A1-TEXT(B1,”h:mm AM/PM”).

## Subtracting With Mixed Date and Time Values

If you have a cell that contains both a date and a time value, then you can subtract the cell from another cell that contains a date or a time value. For example, if cell A1 contains the date and time “1/1/2021 12:00 PM” and cell B1 contains the date “1/1/2021”, then you can subtract the two cells to calculate the difference in time between the two values. The formula to do this is =A1-B1.

### Subtracting With Formulas

You can also subtract dates and times with formulas in Excel. For example, if cell A1 contains the date “1/1/2021” and cell B1 contains the time “12:00 PM”, then you can subtract the two cells to calculate the difference in days between the two values. The formula to do this is =A1-TIMEVALUE(B1).

### Subtracting With Functions

You can also use functions in Excel to subtract dates and times. For example, if cell A1 contains the date “1/1/2021” and cell B1 contains the time “12:00 PM”, then you can subtract the two cells to calculate the difference in days between the two values. The formula to do this is =DATEDIF(A1,B1,”d”).
