Sidereal Sun Sign Dates
Sidereal Capricorn Dates
January 14 to February 11
Lahiri (IAE 1985) ayanamsa · approximate dates for 2020 to 2050 · shifts ~1 day per 72 years
In the Lahiri sidereal zodiac, the Sun enters Capricorn on approximately January 14 and leaves on approximately February 11. This corresponds to most of what tropical astrology calls Aquarius. If you were born between roughly January 14 and February 11, your sidereal Sun sign is Capricorn. January 14 is also the traditional date of Makar Sankranti, the Hindu festival marking the Sun's sidereal entry into Capricorn, one of the clearest cultural anchors for the Lahiri sidereal calendar.
Why does sidereal Capricorn start on January 14?
Sidereal Capricorn begins roughly 24 days after tropical Capricorn. The alignment with Makar Sankranti (January 14) illustrates why the Lahiri ayanamsa is the Indian government standard: traditional Hindu solar festivals are keyed to the sidereal solar calendar, and Lahiri preserves those traditional dates closely.
What if you were born on the cusp?
People born in the last week of tropical Capricorn (roughly January 14 to January 19) are in the cusp zone. Your tropical Sun is Capricorn but your sidereal Sun may also be Capricorn depending on the year. Calculate your sidereal chart to confirm.
