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.
