Sidereal Aries Dates
April 13 to May 13
Usual Lahiri solar month. How these dates are derived
Reviewed
The Sun’s exaltation month in the Lahiri zodiac falls from April 13 to May 13[1]. Indian astrology gives the Sun a place of strength in Aries, with its exaltation point at 10° Aries. Brennan records that degree in the Yavanajataka; the Hellenistic convention instead gives 19° Aries.[4]

Mesha Sankranti belongs to the solar new year season
The Aries ingress is Mesha Sankranti. April solar new year observances include Puthandu in Tamil Nadu and Vaisakhi in Punjab, with Vishu in Kerala and Pohela Boishakh in Bengal.
Krittika begins at 26°40′ Aries, which the Sun usually reaches on May 11. Its first pada completes the Aries solar month; the remaining three padas fall in Taurus.[1]
Ashwini contains the Sun’s exaltation point[1][2][3]
| Nakshatra | Padas | Degrees in Aries | Usual Sun dates (UTC) |
|---|---|---|---|
| Ashwini | 1 to 4 | 0° 00′ to 13° 20′ | April 13 to April 26 |
| Bharani | 1 to 4 | 13° 20′ to 26° 40′ | April 27 to May 10 |
| Krittika | 1 | 26° 40′ to 30° 00′ | May 11 to May 13 |
10° Aries falls before Bharani
Ashwini extends from 0° to 13°20′ Aries, so the 10° exaltation point stands at the junction of its third and fourth padas. The third extends from 6°40′ to 10°, where the fourth begins. In the sampled years, the Sun reaches that degree on April 23 or 24, with each date occurring 25 times.[1] Bharani begins at 13°20′, usually on April 27.
