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.

Every figure here is specific to 21 March: the Moon returns to a given phase on the same calendar date only every 19 years or so, so the counts differ from one date to the next. Mercury’s retrograde periods drift by about 30° of the zodiac each year, which is why the share is near 20% but never identical. How that 20% is computed →

The most frequent is 1 with 12 years; the scarcest is 9 with just 11. And this date can carry a master number: 11 in 11 of those years. Master numbers are never reduced further, which is exactly why they are scarcer than single digits on any fixed day and month. Why 11, 22 and 33 are treated differently →
Why the answer moves
There is no third sign and no blend — at your moment of birth the Sun was one side of the boundary or the other. For 21 March that came out Aries in 97% of years and Pisces in 3%, switching 6 times since 1930. Most recently in 1936, 1939, 1940.
