About the Year Progress Calculator
This year progress calculator shows exactly how far through the year a given moment is — as a percentage, as days elapsed and as time remaining. It also breaks progress down for the current day, week, month and quarter, so you can see at a glance that, say, the year is 74% done while the quarter is almost over.
People use it to check goals and budgets against the calendar (“is our spending ahead of 74% of the year?”), to pace annual reading or fitness challenges, to prorate subscriptions or targets, or simply for the motivating jolt of seeing how much of the year is left. Enter any date and time; the default is a fixed example so the page stays consistent.
Progress is measured in elapsed time from midnight on January 1 to midnight on January 1 of the next year, so leap years count 366 days. Weeks can start on Monday (ISO 8601 standard) or Sunday (common in the US), and quarters are calendar quarters starting in January, April, July and October.
With the default inputs, the year complete is 74.41%. Change any value above to recalculate instantly.
How to use the year progress calculator
- 1Enter the date you want to check.
- 2Enter the time of day for a precise percentage.
- 3Choose whether your week starts on Monday or Sunday.
- 4Read the year percentage and the time left in the year.
- 5Compare day, week, month and quarter progress in the chart and table.
Formula and method
The calculator measures elapsed time from the start of each period to the chosen moment and divides by the period’s full length. For the year, it counts whole days already finished (day of year − 1), adds the fraction of today that has passed, and divides by 365 or 366.
The same idea applies to the other periods: the month uses its actual number of days (28–31), the quarter uses the days in that calendar quarter (90–92), the week uses 7 days counted from Monday or Sunday, and the day uses 24 hours. Remaining percentages are simply 100 minus the elapsed figure. Time zones and daylight saving are ignored; the time is treated as local clock time.
- day of year
- 1 for January 1 through 365 or 366 for December 31
- days in year
- 366 in leap years, otherwise 365
Worked examples
September 29, 2026 at 2:30 pm
September 29 is day 272 of 2026, so 271 full days plus 14.5 hours (0.604 days) have passed: 271.604 ÷ 365 = 74.41%. September is 95.35% done (28.604 of 30 days) and Q3 is 98.48% done (90.604 of 92 days). Tuesday afternoon is 1.604 of 7 days, or 22.92%, of a Monday-start week.
Halfway point of a leap year
2028 is a leap year with 366 days. At midnight starting July 2 exactly 183 days have passed, and 183 ÷ 366 = 50%. The third quarter (92 days) is only 1 day, or 1.09%, in.
New Year’s Eve evening, Sunday-start week
At 6 pm on December 31, 2026 only 6 hours of the year remain: 364.75 ÷ 365 = 99.93% done. December 31, 2026 is a Thursday, so with weeks starting Sunday, 4.75 of 7 days (67.86%) of the week have passed.
Frequently asked questions
What percent of the year has passed?+
Divide the number of days already completed (plus the fraction of today) by 365, or 366 in a leap year. At the end of September 29 in a common year, 272 ÷ 365 ≈ 74.5% of the year is done. Enter any date and time above for the exact figure.
When is the exact halfway point of the year?+
In a common year of 365 days, the midpoint is noon on July 2 (182.5 days in). In a leap year of 366 days it is midnight at the start of July 2, after exactly 183 days.
How many days are left in the year?+
Subtract the day-of-year number from 365 (or 366 in a leap year). On September 29, 2026, day 272, there are 93 full days left after today, plus whatever remains of today itself.
Does the week start on Monday or Sunday?+
The international standard ISO 8601 starts weeks on Monday, which is common in Europe and for business week numbers. Many US calendars start on Sunday. Choose the option you use; it only changes the week percentage.
How is quarter progress calculated?+
Calendar quarters are January–March (90 or 91 days), April–June (91), July–September (92) and October–December (92). Quarter progress is the time elapsed since the quarter began divided by its total length.
