Sagittarius season usually starts around November 22 each year and runs until about December 21.

Exact start date

  • Most modern astrology sources define Sagittarius season as running from November 22 to December 21, when the Sun is in the sign of Sagittarius.
  • In some specific years, the Sun may enter Sagittarius late on November 21 or very early on November 23 depending on time zone and astronomical calculations.

Why dates can vary

  • The Sun does not enter each sign at the exact same clock time every year, so “cusp” dates (around the 21st–23rd) can shift slightly.
  • To know the precise moment Sagittarius season starts for a given year and location, astrologers use an ephemeris or an online birth-chart calculator that tracks the Sun’s exact position.

Quick takeaway

  • For everyday use (horoscopes, pop astrology, general “vibes”), you can safely treat Sagittarius season as:
    • Start: November 22
    • End: December 21

If your birthday falls on November 21–23, you’re on the cusp, and checking your exact birth time and place with a chart calculator will give the most accurate sign.

TL;DR: When people ask “when do Sagittarius season start,” the widely accepted answer is November 22.
