Pisces season usually starts on February 19 and runs until March 20 in most modern Western astrology systems.

Why you sometimes see different dates

You might occasionally see slightly different start dates, like February 18 or even February 20, depending on:

  • The exact year and time zone, since the Sun enters Pisces at a precise astronomical moment.
  • Different astrologers or sites rounding dates or using different ephemeris data.

Because of this, people born right on the cusp (around February 18–20) sometimes need to check a detailed birth chart or year-specific table to know their sign for sure.

If you’re asking “when does Pisces start” in general, the safest, most widely used answer is: February 19.
