How To Calculate the Weeks Until Halloween

You can count down the weeks until Halloween (10/31) in a few ways. The easiest is to use a calculator, such as our weeks calculator. You can also calculate the weeks manually with a calendar or using a spreadsheet formula.

Method One: Use a Calendar

The first method to find how many weeks there are until Halloween is to use a calendar. This method involves a few easy steps.

Step One: Find the Start Date

Begin by identifying the start date on the calendar - you'll need to find both the month and the day.

Step Two: Find the Number of Days Remaining in the Start Month

Beginning with the start month, subtract the day in the start month from the total number of days in that month.

For instance, if the start date is January 7th, and since there are 31 total days in January, there are 31 - 7 = 24 days left in January.

Step Three: Find the Number of Days in the Remaining Months

If there are any remaining full months before Halloween after the start month, then simply add the number of days in each month to the total number of days.

For instance, if the date range is from January 7 to October 31st, then you'll need to add the number of days in the months of February through October to the remaining days in January from step two.

Step Four: Calculate the Number of Days in October

Next, you'll need to find the number of days in October before Halloween. To do this, subtract 1 from 31, which is 30.

Step Five: Calculate the Total Number of Days

The next step is to add up the number of days from steps two, three, and four to calculate the total number of days until Halloween.

Step Six: Calculate the Number of Weeks Until Halloween

The final step is to convert the number of days to weeks to find the number of weeks left until Halloween. To do this, divide the number of days left in the year by 7 to calculate the number of weeks remaining.

Method Two: Use Sheets or Excel

You can also calculate the number of weeks remaining until 10/31 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 weeks remaining from the current day, you can use the following function in a cell to calculate that number:

=INT((DATE(2025, 10, 31) - TODAY()) / 7)

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

From Any Date

If you want to find the number of weeks 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 weeks remaining from the date displayed in cell A1:

=INT((DATE(2025, 10, 31) - A1) / 7)
