Month-by-month reference
Zodiac Calendar by Month
See which two tropical zodiac signs appear in each calendar month, where the approximate transition falls, and when an exact chart calculation is needed.
How to use this calendar: Choose a month for a clear day-by-day overview. Common boundaries are approximate because the Sun changes signs at a specific time that varies by year and time zone.

The tropical zodiac contains twelve equal 30-degree signs, while the civil calendar contains twelve unequal months. Their boundaries therefore do not line up. Most sign changes occur between the 18th and 23rd day of a month.
Use a calculation for transition dates
People born near a sign change should not rely on a generic table. Use birth year, time and location to identify the Sun’s exact zodiac longitude.
