How to use it
- See the days left in the year at the top.
- Check the day of the year, the percentage and the weekdays left.
- Pick any date to see how many days until (or since) it.
Day of the year and days left
The page shows today's day number (January 1 is day 1, December 31 is day 365, or 366 in a leap year) and the number of days left in the year, not counting today. A progress bar and percentage show how much of the year has gone by.
Example: November 13, 2026 is day 317 of 2026. There are 48 days left in the year, and about 86.8% of the year has passed.
Weekdays left
Below the progress bar you'll see how many weekdays (Monday to Friday) remain after today through December 31. It doesn't subtract holidays, since those differ by employer and state. In most of the U.S., the late-year federal holidays are Veterans Day (November 11), Thanksgiving (fourth Thursday in November) and Christmas Day (December 25).
Days until any date
Pick a date in the box below to see how many days are left until it, or how many days have passed since it if it's in the past. Use it for deadlines, trips, school breaks, due dates or anniversaries. For a live countdown with hours and minutes, use the countdown to a date. To count between two dates other than today, use the date calculator.
Leap years
A year has 366 days if it's divisible by 4, except century years, which must be divisible by 400. So 2024 and 2028 are leap years, 2100 isn't, and 2000 was. In a leap year every date after February 28 has a day number one higher than usual: March 1 is day 61 instead of day 60.
| Date | Day number (common year) | Day number (leap year) |
|---|---|---|
| January 31 | 31 | 31 |
| March 1 | 60 | 61 |
| July 4 | 185 | 186 |
| October 31 | 304 | 305 |
| December 31 | 365 | 366 |
Why people track the day of the year
Day numbers are used in some date formats (for example ordinal dates like 2026-317), in shipping and manufacturing codes, in agriculture and science, and by anyone doing a "365-day challenge". The counter uses your device's date and runs in your browser.
Quarters of the year
| Quarter | Months | Last day (common year) |
|---|---|---|
| Q1 | January–March | day 90 (March 31) |
| Q2 | April–June | day 181 (June 30) |
| Q3 | July–September | day 273 (September 30) |
| Q4 | October–December | day 365 (December 31) |
Add one to each day number in a leap year.
