Calculating…
The Sun is in sidereal Aquarius from February 12, 2026 to March 14, 2026 in 2026, calculated with the Lahiri ayanamsa. This window covers most of what tropical astrology labels Pisces season — people classified as tropical Pisces who experience more intellectual detachment and collective orientation than oceanic empathy may be operating from a sidereal Aquarius Sun.
Tropical astrology places Aquarius from January 20, counted from the vernal equinox. Sidereal astrology places it at the Aquarius constellation's actual sky position, which the Sun reaches approximately February 12. The ~24.21° gap equals Earth's precession since the systems last aligned in ~285 CE: roughly 1,740 years × 50.3 arcseconds per year. The Lahiri ayanamsa, India's official astronomical standard since 1955, subtracts this accumulated drift from tropical longitudes for every body in the chart. The result: most tropical Pisces Sun people (born February 19 – March 13) are sidereal Aquarius under Lahiri. Astronomically, the Sun physically enters the Aquarius star region — a constellation containing the notable star Sadalsuud (β Aquarii, the luckiest star) — around mid-February each year, not late January.
Why sidereal differs from tropical →
The Aquarius ingress shifts roughly 20 minutes later per decade as the Lahiri ayanamsa increases by ~50.3 arcseconds annually. In 2026 the Sun enters sidereal Aquarius around February 12 and exits around March 14. Year-to-year variation is a matter of hours. The seven-year table below shows Swiss Ephemeris entry and exit times for 2023–2029, computed with SEFLG_MOSEPH and Lahiri ayanamsa. Anyone born near the February 11–13 window where sidereal Capricorn transitions to Aquarius should verify their specific year's ingress time — at roughly 12 hours of annual shift, a two-year span can push the boundary by a full day.
