About this year progress calculator
A year-progress meter tells you how much of a calendar year is already gone, expressed as a percent with two decimals plus the equivalent day-of-year. The tool measures progress in your local timezone, treating the year as the span from 1 January at midnight to 1 January of the following year at midnight, and updates once per second so you can watch the value tick over without refreshing the page.
Internally, it converts your year into a start/end timestamp pair, subtracts <code>Date.now()</code> from the start, divides by the total duration, and rounds to two decimal places. Day-of-year is computed via cumulative month lengths with a leap-year adjustment, so years with 366 days are reported correctly. The ISO week comes from the standard Thursday-of-week algorithm.
Worked example: on 28 May 2026 at 10:00 local time, ask for the year 2026. The tool reports approximately 40.5% complete, day 148 of 365, 217 days remaining, and ISO week 22. The progress bar fills proportionally to 40.5% and continues to nudge upward each second.
Useful for goal-tracking, fiscal-year planning, social posts ("the year is X% over"), or simply a daily reality check on how time is flying.
FAQ
- What timezone does the progress use?
- Your browser’s local timezone. The year starts at midnight 1 January in your zone and ends at midnight 1 January of the next year.
- Does the bar update automatically?
- Yes — once you press Show year progress, the value recalculates every second. Reset stops the live update.
- Is the day-of-year leap-year aware?
- Yes. February 29 counts as day 60 in leap years and the total span is 366.
- Can I check a previous year?
- Yes. Past years will show 100% with day 365 (or 366) and 0 days remaining. Future years show 0% with the full year remaining.
