Calculating dates in Google Sheets is a crucial task for many users, especially those who work with data related to schedules, events, and timelines. Whether you’re a student, a professional, or a business owner, being able to calculate dates accurately is essential for making informed decisions and staying organized. In this blog post, we’ll explore the various ways to calculate dates in Google Sheets, from simple arithmetic operations to more complex date and time calculations.
Understanding Dates in Google Sheets
In Google Sheets, dates are represented as a numeric value that represents the number of days since January 1, 1900. This is known as the “serial date” or “serial number” format. When you enter a date in a cell, Google Sheets automatically converts it to this serial number format. This allows you to perform arithmetic operations on dates, such as adding or subtracting days, months, or years.
When working with dates in Google Sheets, it’s essential to understand the date format used by the spreadsheet. By default, Google Sheets uses the “MM/DD/YYYY” format, but you can change this to a different format using the “Date format” option in the “Number” format dropdown menu.
Basic Date Calculations
One of the most common date calculations in Google Sheets is adding or subtracting days, months, or years from a date. This can be done using simple arithmetic operations, such as:
| Operation | Formula |
|---|---|
| Adding days | =A1+1 |
| Subtracting days | =A1-1 |
| Adding months | =A1+30 |
| Subtracting months | =A1-30 |
| Adding years | =A1+365 |
| Subtracting years | =A1-365 |
For example, if you want to add 10 days to the date in cell A1, you would use the formula =A1+10. If you want to subtract 3 months from the date in cell A1, you would use the formula =A1-90 (since there are approximately 30 days in a month).
Date and Time Calculations
In addition to basic date calculations, Google Sheets also allows you to perform more complex date and time calculations. For example, you can use the `TODAY()` function to get the current date and time, or the `NOW()` function to get the current date and time with a specified time zone.

You can also use the `DATE()` function to create a date from a specific year, month, and day, or the `TIME()` function to create a time from a specific hour, minute, and second. For example:
| Function | Formula |
|---|---|
| TODAY() | =TODAY() |
| NOW() | =NOW() |
| DATE() | =DATE(2022, 6, 15) |
| TIME() | =TIME(12, 30, 0) |
You can also use the `DATEDIF()` function to calculate the difference between two dates, or the `EOMONTH()` function to get the last day of the month. For example:
| Function | Formula |
|---|---|
| DATEDIF() | =DATEDIF(A1, B1, “D”) |
| EOMONTH() | =EOMONTH(A1, 0) |
Working with Date Ranges
Another common task in Google Sheets is working with date ranges. This can include calculating the number of days between two dates, or identifying dates that fall within a specific range. To do this, you can use the `DATEDIF()` function in combination with the `MIN()` and `MAX()` functions.
For example, if you want to calculate the number of days between two dates, you can use the formula:
| Formula | Description |
|---|---|
| =DATEDIF(A1, B1, “D”) | Calculates the number of days between the dates in cells A1 and B1 |
Alternatively, if you want to identify dates that fall within a specific range, you can use the `IF()` function in combination with the `DATE()` function. For example: (See Also: Why Is Google Sheets Not Summing Correctly? Common Mistakes Revealed)
| Formula | Description |
|---|---|
| =IF(A1>=DATE(2022, 6, 1) AND A1<=DATE(2022, 6, 30), "June 2022", "") | Identifies dates that fall within the range of June 1, 2022 to June 30, 2022 |

Frequently Asked Questions
Q: How do I calculate the number of days between two dates in Google Sheets?
A: You can use the `DATEDIF()` function to calculate the number of days between two dates. For example, the formula =DATEDIF(A1, B1, “D”) calculates the number of days between the dates in cells A1 and B1.
Q: How do I get the current date and time in Google Sheets?
A: You can use the `TODAY()` function to get the current date, or the `NOW()` function to get the current date and time. For example, the formula =TODAY() returns the current date, while the formula =NOW() returns the current date and time.
Q: How do I create a specific date in Google Sheets?
A: You can use the `DATE()` function to create a specific date. For example, the formula =DATE(2022, 6, 15) returns the date June 15, 2022.
Q: How do I calculate the difference between two dates in Google Sheets?
A: You can use the `DATEDIF()` function to calculate the difference between two dates. For example, the formula =DATEDIF(A1, B1, “D”) calculates the number of days between the dates in cells A1 and B1.
