## How To Calculate the Days Until September 21st

You can count down the days until 9/21 in a few ways. The easiest is to use a calculator, such as our days until date calculator. You can also calculate the days manually or use a spreadsheet formula.

### Method One: Calculate the Days Manually

If the current date falls in September, then you can simply subtract the current day of the month from 21. The resulting value is the number of days remaining.

days until 9/21 = 21 – current day in September

If the current date is not in September, then you can subtract the current day of the month from the number of days in the current month to find the remaining days in that month. Then, to that value, you can add the number of days in each month before September, and then add 21 for the number of days in September.

days until 9/21 = days left in the current month + days in next month + … + 21

### Method Two: How To Calculate the Days Using Google Sheets

You can also calculate the number of days remaining until 9/21 using spreadsheet software such as Google Sheets or Microsoft Excel. You can do this using a few different formulas.

### From the Current Date

If you want to find the number of days remaining from the current day, you can use the following function in a cell to calculate that number:

=DATE(2024, 9, 21) - TODAY()

Note that this formula calculates and displays the number of days once you type the formula into a cell and hit Enter.

### From Any Date

If you want to find the number of days remaining from a specific date listed in another cell, in this case, from a date in cell A1, then you can use the following function to display the number of days remaining from the date displayed in cell A1:

=DATE(2024, 9, 21) - A1
