Sun in Sidereal Aries: April 14, 2026 – May 15, 2026 (2026)

The Sun is in sidereal Aries from April 14, 2026 to May 15, 2026 in 2026, computed with the Lahiri ayanamsa. That places the window roughly 24 days after tropical Aries opens on March 20–21 — the accumulated gap between the fixed equinox point and the actual Aries star pattern, currently about 24.21°.

Why these dates differ from tropical astrology

Tropical astrology anchors Aries to the vernal equinox: March 20–21 every year, fixed by definition. Sidereal astrology anchors it to the Aries constellation itself. Earth’s axial wobble — precession — moves the equinox westward against the stars at about 50.3 arcseconds per year. That rate compounds: over 2,000 years the equinox has drifted nearly 28°. The Lahiri ayanamsa, codified by the Indian government in 1955 and now the standard for Vedic astrology, quantifies this drift at approximately 24.21° as of 2026. Subtracting that value from the tropical Sun longitude gives the Sun’s position relative to the true Aries star band. So when the Sun crosses 0° sidereal Aries — the border between Pisces and Aries stars — it has already been at 0° tropical Aries for three weeks.

How dates shift year over year

The Lahiri ayanamsa grows by roughly 50.3 arcseconds each year. That sounds precise — and it is. In daily terms it shifts the Aries entry point by about 20 minutes per decade, less than half an hour over ten years. For most purposes the date is stable: April 14 in 2026, April 14 in 2036, April 14 in 2046, with only the hour of day varying. The exact UTC ingress time matters most if you were born within 24 hours of the Aries–Pisces boundary and want to confirm which sign your Sun occupies. The seven-year table below gives UTC precision for 2023–2029.
