Equinox and solstice dates by year, 2029–2033

Choose a year for the exact Universal Time of both equinoxes and both solstices. Each page also includes Earth’s perihelion and aphelion from the same official U.S. Naval Observatory annual dataset.

Five-year canary archive

This is a deliberately bounded first release: five annual references, not hundreds of lightly differentiated pages. Every date is stored in a checked-in source snapshot, each annual page answers the year-specific query directly, and production builds do not call an external API.

What the annual pages show

The exact UT date and minute of the March and September equinoxes.
The exact UT date and minute of the June and December solstices.
Perihelion and aphelion, when Earth is nearest to and farthest from the Sun during that year.
A clear reminder that converting an instant from UT can change the local date in some time zones.

Source and scope

The archive is based on the official USNO Earth’s Seasons service. USNO provides seasonal and apside data from 1700 through 2100; SkyClock currently publishes only 2029–2033 as a measured canary. The checked-in API snapshot was retrieved 2026-09-20 from API version 4.0.1.

The event names follow the conventional Northern Hemisphere labels used by USNO. The astronomical instants are global; local civil dates can differ after time-zone conversion. These references are for general planning and education, not navigation or safety-critical decisions.
