How to Calculate How Many Weeks Are Left in the Year

There are several ways to determine the number of weeks remaining in a year. You can use a calculator, such as a weeks-between-dates calculator, or calculate it manually. Here are the main methods:

Method One: Use a Calendar

Find the Start Date
Identify the starting date by noting the month and day.

Calculate the Remaining Days in the Start Month
Subtract the current day from the total number of days in the month.
Example: If the date is June 3 and June has 30 days:

30 – 3 = 27 days remaining in June

Add the Days in the Remaining Months
Sum the total days for the months left in the year after the start month.
Example: From June 3 to December 31, add the days in July through December to the remaining 27 days of June.

Calculate Total Days Left
Add the remaining days from the start month to the days in the remaining months to get the total days left in the year.

Convert Days to Weeks
Divide the total days left by 7 to get the number of weeks remaining:

Weeks remaining = Total days left ÷ 7

Method Two: Subtract the Current Week Number

If you know the current week number, you can calculate the weeks remaining by subtracting it from the total weeks in the year (52 or 53, depending on ISO-8601):

Weeks left = 52 – Current week number

Example: If it’s currently week 44, then:

Weeks left = 52 – 44 = 8 weeks remaining

Method Three: Use Google Sheets or Microsoft Excel

You can also calculate weeks remaining using a spreadsheet.

Whole Weeks Left
To find the number of full weeks left after today:

=INT((DATE(YEAR(TODAY()), 12, 31) – TODAY()) / 7)

Example: If today is October 31, this formula calculates the remaining full weeks.

Rounded Weeks Left
To find the weeks left rounded to the nearest whole week:

=ROUND((DATE(YEAR(TODAY()), 12, 31) – TODAY()) / 7, 0)

These formulas can also be adapted to calculate dates 4 weeks, 6 weeks, or 8 weeks from today.
