The gap comes from the precession of the equinoxes. The Earth's axis slowly traces a cone, like a spinning top, so the equinox point slides back against the stars by about 50 arcseconds a year: one degree every 72 years and a full circle in roughly 26,000 years. With the formula used here, the two zodiacs lined up around the year 290; today the gap (the ayanamsa) is over 24°, which pushes every sign change back by about 24 days. That is why Thai signs change around the 13th to 17th of each month rather than the 20th to 23rd.

Why the two zodiacs drift apart
The Earth's axis wobbles slowly like a spinning top. The starting point of the Western zodiac (the March equinox) therefore slides against the stars, by about one degree every 72 years. Move the year to watch the gap grow and the Sun's entry into Mesha move later in the calendar.
- Gap (ayanamsa)
- Gap between the zodiacs: 24.2°
- Sun enters Mesha
- The Sun enters Mesha on 14 April
The two zodiacs matched around the year 293 (Lahiri formula). A full circle takes about 25,800 years.
Dates use the Gregorian calendar extended into the past; before 1582 people used other calendars, so the drift of Songkran is illustrative.
