Earth Day 2026 has already happened. It was Wednesday, 22 April 2026, 128 days ago. This page is kept whichever side of today the date falls on: the date and the rule behind it are worth looking up either way. For the year after this one see Earth Day 2027, and for the always-current countdown see the next Earth Day.
Earth Day 2026 is Wednesday, 22 April 2026
Earth Day 2026 fell on Wednesday, 22 April 2026, which was 128 days before 28 August 2026. That is 18 weeks and 2 days, or 89 working days once Saturdays, Sundays and the US federal holidays in between are taken out — the figure that matters if you are counting delivery lead time or a work schedule rather than sleeps. The date is 2026-04-22 in ISO form and 4/22/2026 in the US format, it falls in ISO week 17 of 2026, and it is day 112 of 365.
How the date of Earth Day is decided
Earth Day is always 22 April.
That makes it a fixed date: the same day of the same month every year, so it lands on a different weekday each time. In 2026 it is a Wednesday.
Earth Day is an observance rather than a federal holiday. Offices, banks and schools stay open unless an individual employer chooses otherwise, and it counts as an ordinary business day in every calculator here. Only the eleven federal holidays are treated as non-working days — the list and the reasoning are on the holiday sources page.
Earth Day in the years after 2026
| Year | Date | Day | Countdown |
|---|---|---|---|
| 2027 | 22 April 2027 | Thursday | Earth Day 2027 |
| 2028 | 22 April 2028 | Saturday | Earth Day 2028 |
| 2029 | 22 April 2029 | Sunday | Earth Day 2029 |
The date does not move, but the weekday does — which is why the same holiday gives a long weekend in some years and not others.
Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including how we count the 89 working days above.
