The 354th day of the year, the 355th in a leap year

Born on 20 December

Every 20 December birthday from 1920 to 2026 was Sagittarius in UTC, and in most of the world. In 3 of those years the sun changed sign within hours of the date, and by the clocks somewhere far enough east or west of Greenwich it was 20 December when it happened; see below.

Crossings within hours of 20 December

A date begins earlier east of Greenwich and later to the west, so in these years the sun changed sign on the day before or after in UTC, at a moment when clocks somewhere on earth already, or still, showed 20 December — worked out from the time zones in use at that moment, as the IANA time zone database records them. A birth there on 20 December that year could be either sign, and the calculator above works it out for your own time zone.
