Epoch columns are UTC: "Start" is 00:00:00 on the Monday, "End" is 00:00:00 on the Sunday — the first second of the last day, not the last second of the week. For week 1 of 2030, that end value is 1893888000; add 604,799 to any start epoch to land on the week's final second (Sunday 23:59:59).

How to read this table

  • Week # — the ISO 8601 week number for that week.
  • ISO year — the ISO week-numbering year this week belongs to (can differ from the calendar year for a few edge days).
  • Monday start — the date of the Monday that starts the week, in UTC.
  • Sunday end — the date of the Sunday that ends the week, in UTC.
  • Start epoch (UTC) — Unix timestamp for 00:00 UTC on Monday.
  • End epoch (UTC) — Unix timestamp for 00:00 UTC on Sunday.

Reading 2030's weeks as epoch ranges

A Unix timestamp pins an instant; an ISO week names a seven-day span. Reporting tools constantly translate between the two — a log line becomes "week 9", or a weekly report becomes an epoch range to query. In 2030, that mapping is concrete: week 1 opens at epoch 1893369600, and week 52 closes at 1925337599, the final second of Sunday, Dec 29, 2030.

  • Epoch 1893369600 → 00:00 UTC on Monday of week 1 (Dec 31, 2029).
  • Epoch 1925337599 → 23:59:59 UTC on Sunday of week 52 — one second before 1925337600 would tick over to the next ISO year's week 1.
  • Any week's span → its start epoch up to start + 604,799 seconds; exactly 604,800 seconds per week, no exceptions (UTC has no DST).

Why 2030 has 52 weeks

The count falls out of one rule: ISO week 1 is the week containing the first Thursday, and weeks run Monday–Sunday. 2030 starts on a Tuesday, which keeps it a 52-week year; the days after week 52 belong to week 1 of 2031. December 31, $2030 closes on a $Tuesday, and the last week ends $on Dec 29, 2030, still inside 2030

How 2030's weeks line up against neighboring years

The same calendar date rarely keeps its week number from one year to the next, because each January 1 lands on a different weekday. March 1, 2030 sits in ISO week 9; in 2029 and 2031 it will sit one week off in either direction. The tables for the adjacent years make the drift visible:

Examples: 2030's weeks at the epoch boundaries

  • January 1, 2030 (Tuesday) falls in ISO week 1 of ISO year 2030.
  • December 31, 2030 (Tuesday) falls in ISO week 1 of ISO year 2031.
  • March 1, 2030 sits in ISO week 9 — the sort of date whose week number shifts year to year.

Week Numbers for 2030 — ISO Week List — questions from actual use

What are the week numbers for 2030?

2030 has 52 ISO weeks. Week 1 runs Dec 31, 2029 to Jan 06, 2030 — it starts in December 2029, because ISO week 1 is the week containing the first Thursday, and 2030's first Thursday pulls the week start back into 2029, and week 52 runs Dec 23, 2030 to Dec 29, 2030.

Is 2030 a 52-week or 53-week year?

2030 is a 52-week year (January 1 was a Tuesday). The next 53-week year is 2032, because its January 1 falls on the right weekday to spill into a 53rd week.

When do 2030's week numbers and dates disagree?

Day-of-year and week-of-year counting disagree at the edges. January 1, 2030 (Tuesday) sits in ISO week 1 of 2030, and December 31 (Tuesday) lands in week 1 of 2031 — already week 1 of 2031. The ISO year owns the days its weeks' Thursdays fall in, so a few days each December and January always belong to the neighboring year.

What epoch timestamps belong to a week in 2030?

Each week on this page shows two Unix timestamps: 00:00 UTC on its Monday (the start) and 00:00 UTC on its Sunday. For 2030, those run from 1893369600 for the start of week 1 to 1925337599 for the last second of week 52 — a span of exactly 31,449,600 seconds across 52 weeks.
