January 21 zodiac sign: Aquarius

Where in Aquarius this falls
January 21 falls on day 2 of the Venus decan (20–January 29, 2026).
- Aquarius at midday UTC
- Sign changed during the day (UTC)
- 2026
Aquarius at midday UTC in all 100 years, but in 10 of them — 1931, 1932, 1936, 1940, 1944, 1948, 1952, 1956, 1960 and 1964 — the Sun changed sign during January 21 itself (UTC), so a birth in the first hours of that day could still be Capricorn.

Venus softens the sign toward attachment and taste, aiming the same drives at being liked. In its first ten degrees Aquarius shows in its rawest form: Capricorn has only just handed over, and nothing of the new sign has worn down yet.

The Moon and nakshatra columns change every year because the Moon returns to the same calendar date in a different position — which is why a birth date alone cannot tell you those, and why this table exists.

The most frequent is 8 with 12 years; every other number, 11 included, turns up in 11 years. And this date can carry a master number: 11 in 11 of those years — kept whole rather than reduced. Why 11, 22 and 33 are treated differently →
Why the answer almost always holds
January 21 sits 1 day past the start of Aquarius and reached 1°26′ this year — close enough to the start of the sign that the hour starts to count: in 10 of those 100 years a birth early in the day (UTC) had the Sun still in Capricorn. At midday it is Aquarius in every year tested, so on this date the question worth asking is the birth time, not the birth year.
