Year Progress Calculator

How it works

progress = time elapsed since the period began ÷ length of the period × 100 (365 or 366 days for a calendar year) · days left = length − elapsed · the same ratio for the day, week, month, quarter, decade and century · milestone date = start + length × p%

A progress bar for the calendar. The days that have passed since January 1, divided by 365 (or 366 in a leap year), give the share of the year that is gone; the week, month, quarter, decade and century use the same idea. By default the chosen date counts as just starting, so only the full days before it are counted. Switch to End of day to count the date as done, which is how many “year progress” sites show it, or pick a time to get the figure to the minute. Choose Fiscal year to measure a year that ends in another month, such as September 30 for the US federal government, or My own dates for any stretch of time: a semester, a project, a contract or a training plan. The results also show the days, weekdays, weekends and hours left, the day and ISO week number, and what 1% of the period is worth. The milestones table gives the date and time each of 10%, 25%, 50%, 75% and 90% is reached, and the month-by-month table shows how far through each month you are.

Worked example

At the start of October 18, 2026 (day 291 of 365), 290 full days have passed: 290 ÷ 365 = 79.5% of the year, leaving 75 days or 10.7 weeks, with 10 weekends and 54 weekdays. At the end of that day it is 291 ÷ 365 = 79.7%. October is 55% done, Q4 is 18% done, the 2020s are 67.9% through and the 21st century 25.79%. The year hit 50% at noon on Thursday, July 2. For a school year from September 1, 2026 to June 30, 2027 (303 days), October 18 is 47 ÷ 303 = 15.5% of the way through.
