Sun in Sidereal Scorpio: November 16, 2026 – December 16, 2026 (2026)

The Sun is in sidereal Scorpio from November 16, 2026 to December 16, 2026 in 2026, calculated with the Lahiri ayanamsa. This window covers the last days of tropical Scorpio season and the first three weeks of tropical Sagittarius — meaning many who identify as tropical Sagittarius but find the philosophical restlessness uncharacteristic may be working from a sidereal Scorpio Sun instead.

Why these dates differ from tropical astrology

Tropical astrology starts Scorpio at October 23, anchored to the ecliptic counted from the vernal equinox. Sidereal astrology starts it when the Sun reaches the actual Scorpius constellation — roughly 25 days later. The ~24.21° gap between the zodiacs equals Earth's accumulated precession since the systems were last aligned in ~285 CE: approximately 1,740 years × 50.3 arcseconds per year. The Lahiri ayanamsa, India's official standard since 1955, corrects for this by subtracting the accumulated drift from every tropical longitude. Swiss Ephemeris applies this correction to every planetary position, placing Scorpio's boundaries about three and a half weeks later than tropical charts show. The practical consequence: most people born in the first three weeks of tropical Sagittarius season (November 22 – December 15) are sidereal Scorpio under the Lahiri calculation.

How dates shift year over year

The sidereal Scorpio window shifts roughly 20 minutes later per decade as the Lahiri ayanamsa increases by ~50.3 arcseconds each year. In 2026 the Sun enters sidereal Scorpio around November 16 and exits around December 16 — the same calendar dates hold across modern decades, with only hours varying in UTC. The seven-year table below lists exact Swiss Ephemeris entry and exit times for 2023–2029, computed with SEFLG_MOSEPH and Lahiri ayanamsa mode. Anyone born November 14–18 should check their specific birth year's ingress time to confirm whether the Sun was in sidereal Libra or Scorpio — the sign boundary crosses this window.
