The 266th day of the year, the 267th in a leap year
Born on 23 September
In UTC, since 1920, 23 September has been Virgo all day in 3 years and Libra all day in 23 years. In the other 81, the sun moved from Virgo into Libra during the day, so a birthday then is Virgo or Libra depending on the hour; the table below gives the moment. Those are UTC days: in 26 more years a crossing on the day before or after fell on 23 September by the clocks somewhere east or west of Greenwich, listed below the table.

The September equinox
23 September has been the September equinox's usual date: between 1920 and 2026 the sun entered Libra on it, in UTC, in 81 years. In 2026 it did so at 00:06 UTC, the earliest time in the whole period.
That early start meant that a 2026 birthday on this date hardly depended on the hour in UTC, since only the first few minutes were Virgo; in New York, where it was still 22 September at 20:06, the whole of 23 September 2026 was Libra. Other years split the day more evenly: in 2019 the equinox came at 07:50 UTC, and in 2023 at 06:50 UTC.
The exceptions have moved from one end of the period to the other. In 1923, 1927 and 1931 the equinox waited until the 24th and a 23 September birthday was Virgo all day; since 1968 it has come on the 22nd in 23 years, and in those it was Libra from the first minute.

Which sign, by year
The sun moves from Virgo into Libra at an instant that falls about six hours later each year and jumps back most of a day at each leap year. On 23 September that instant has fallen inside the day in 81 years since 1920; those years show the moment, in UTC and to the minute. A birth before it is Virgo, after it Libra. To read one of these times on your own clock on 23 September, add your time zone's offset east of Greenwich or subtract it to the west, or put the year into the calculator above, which works in your own time zone.

Other time zones
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 23 September — worked out from the time zones in use at that moment, as the IANA time zone database records them. A birth there on 23 September that year could be either sign, and the calculator above works it out for your own time zone.
