Weeks Left in the Year Calculator
As of October 18, 2026 (US Eastern time), there are 10 full weeks left in 2026 (74 days after today, plus 4 leftover days). Today is not counted.
See how many weeks are left in the year from today: whole 7-day blocks from tomorrow to December 31, plus the days that do not fill a week. After today, October 18, 2026, there are 74 days, which is 10 weeks and 4 days. The card also counts the weekends still ahead, fortnights and US weekdays. For a single day count use the days left counter, or see how much of the year has passed as a percent.
Quick answer: Count the days after today through December 31, divide by 7 and keep the whole number. The remainder is the leftover days. Today is not counted. A common year has 365 days, which is 52 weeks and 1 day, and a leap year has 366, or 52 weeks and 2 days.
How weeks left are counted
The page counts calendar days after today through December 31, then splits them into weeks of 7. So 93 days after today becomes 13 whole weeks and 2 leftover days. The ISO week number is shown for context only. It is not used in the sum, because a 53-week ISO year would throw the answer off.
Worked example: a goal set in early March
Say someone sets a fitness goal on Tuesday, March 3, 2026, and wants to know how many full training weeks remain this year.
January has 31 days and February has 28, so March 3 is day 62. The year 2026 is not a leap year, which leaves 365 − 62 = 303 days after it.
Seven goes into 303 forty-three times, using 301 days. That leaves 2 extra days at the end of December.
Result: 43 whole weeks and 2 days are left in 2026 after March 3.

Work weeks and paychecks left
Weeks on this page are plain 7-day blocks. A work week is five weekdays, so divide the weekdays left by 5 for the work weeks still ahead. The card shows US weekdays with federal holidays already taken out. From mid-October, Veterans Day (November 11), Thanksgiving (November 26) and Christmas Day (December 25) all come off that count.
Paychecks depend on your pay dates rather than the calendar. On a biweekly schedule, count every second payday until December 31. The pay period calendars list them for each year, and paydays until Christmas counts the ones before December 25.
Weeks left in Excel or Google Sheets
Each formula measures from today to December 31 of the current year. Format the cells as numbers so the answers do not show up as dates.
| What you want | Formula |
|---|---|
| Whole weeks left | =INT((DATE(YEAR(TODAY()),12,31)-TODAY())/7) |
| Leftover days | =MOD(DATE(YEAR(TODAY()),12,31)-TODAY(),7) |
| Weeks left as a decimal | =(DATE(YEAR(TODAY()),12,31)-TODAY())/7 |
| Saturdays (weekends) left | =NETWORKDAYS.INTL(TODAY()+1,DATE(YEAR(TODAY()),12,31),"1111101") |
| Work weeks left, Monday to Friday | =NETWORKDAYS(TODAY()+1,DATE(YEAR(TODAY()),12,31))/5 |
| Today's ISO week number | =ISOWEEKNUM(TODAY()) |
The weekend formula uses a pattern of seven digits, Monday first. A 0 marks a day to count, so "1111101" counts only Saturdays.
Common mistakes
- Taking the week number away from 52. ISO years have 52 or 53 weeks, and 2026 has 53. Week numbers also start on Monday, so the result can be off by a week. Count days instead.
- Counting today. Today is already under way, so the count starts tomorrow. On December 31 the answer is 0 weeks and 0 days.
- Rounding up the last partial week. Four days at the end of December are leftover days, not a week.
- Treating weeks left as work weeks left. Holidays such as Thanksgiving and Christmas fall in the last weeks of the year. Use work days left for working days.
