Equinoxes and Solstices

Published on 2025-12-21, updated on 2026-09-23

This page shows the times for each equinox and solstice from the year 1900 to the year 2100: first as a set of distribution charts, then as a full table.

The data is produced by the Python library Skyfield, which in turn is based on data from NASA's Navigation and Ancillary Information Facility (NAIF).

The figures below show the distribution of March equinoxes, June and September equinoxes, and December solstices by day and hour (1900-2100). Note that the UTC time zone has been used here. The distribution will be shifted accordingly in other time zones.

March Equinox Distribution by Day and Hour (1900-2100)

June Solstice Distribution by Day and Hour (1900-2100)

September Equinox Distribution by Day and Hour (1900-2100)

December Solstice Distribution by Day and Hour (1900-2100)

Each row in the following table represents a year, each column represents a month. Each cell shows the day of month followed by a timestamp in UTC.

Some quick links to jump to specific years: 2000, 2026.
