April 22 is civic Earth Day: the 1970 US teach-in date that later went worldwide. It is not a federal closing and not the March equinox. This clock aims at your local April 22, then at the next April 22 after that date finishes. 2026 falls midweek on the 22nd; 2027 falls on a Thursday. Volunteer events often slide to the nearest Saturday. Keep this slug on the 22nd so the 1970 anniversary does not vanish into a cleanup weekend. Share the same URL in January; April 22 is what the clock will keep naming.
FAQ
- When is Earth Day?
- April 22 every year. After that local date ends, we roll to next April 22. 2026 is a Wednesday; 2027 is a Thursday. The heading stays yearless.
- Is it a federal holiday?
- No. Schools and workplaces are typically open; many host volunteer events, cleanups, or classroom lessons. A closed campus is a local choice, not a statute.
- When did Earth Day start?
- The first Earth Day was April 22, 1970, organized in the United States by Senator Gaylord Nelson with Denis Hayes and others as a coast-to-coast teach-in. The Environmental Protection Agency opened later that same year — adjacent history, not the same event.
- Why might another site disagree?
- Some environmental calendars highlight the March equinox as a planetary “earth day.” Modern civic Earth Day is April 22. A UTC flip can also shift the count near midnight.
- Why April 22, specifically?
- Unique to this page: Nelson picked a weekday between spring break and final exams so college teach-ins could actually fill — a campus-calendar choice, not an equinox calculation. That is why Earth Day is a fixed April date while astronomical seasons keep moving.
- Should I count to a cleanup start time?
- Use a custom time for a city's event. This page stays on April 22 so a shared link means the civic date.
- How should a school or city cleanup use April 22?
- Teach-ins and litter pickups often slide to the nearest Saturday, especially when April 22 is a Wednesday (2026) or Thursday (2027). Keep this page on the 22nd so the 1970 anniversary stays visible; attach a custom Saturday morning clock for the gloves-and-bags event. Equinox celebrations are a third, astronomical calendar — do not merge them here.
- Is Earth Day connected to the EPA's birthday?
- The EPA opened in December 1970, months after the first Earth Day teach-in. Adjacent, not identical. Do not retarget this April 22 clock at a December agency anniversary.
