Today's row is highlighted by position in the list — look for day $— when $2023 is the current year.

How to read this table

  • Day # — the day-of-year number, 1-based. January 1 is day 1.
  • Date — the calendar date in UTC.
  • Day — the day of the week (Sunday–Saturday).
  • Week # — the ISO 8601 week number for that date.
  • Epoch (UTC) — the Unix timestamp for 00:00 UTC on that date.
  • Days left — how many days remain in the year after this date.

Why include the epoch timestamp for every day

The Unix epoch timestamp is the number of seconds since January 1, 1970, 00:00:00 UTC. Pairing a day number with its epoch makes this page useful for two tasks at once: finding "what day of the year is it" and finding the epoch for any day of the year. Copy any epoch value in the table, paste it into the epoch converter, and you get the date back — or go the other way with the date to epoch converter.

Examples

  • January 1, $2023 → day 1, $Sun$ $Sun, epoch $1672531200.
  • February 1, $2023 → day $32 $Wed, ISO week $5, epoch $1675209600.
  • March 1, $2023 → day $60, $Wed, epoch $1677628800.
  • December 31, $2023 → day $365, $Sun, epoch $1703980800, 0 days remaining.

Year-to-year comparison

Day numbers are the same for every common year when you ignore the calendar date: day 60 is always the 60th day, but the calendar date it falls on depends on whether February has 28 or 29 days. Compare a few:

More timestamp tools

Need the reverse direction, another precision, or a whole list at once? The epoch time converter on the home page converts dates to Unix timestamps and back — seconds, milliseconds, or microseconds — with batch conversion, and the Unix timestamp to date converter handles one value at a time.

Prefer reading? The guides explain Unix time, timestamp formats, and common bugs in depth, and the methodology page documents exactly how this site handles negative timestamps, fractional seconds, leap seconds, and daylight-saving transitions.
