Dakshinayan

Dakshinayan begins from 21/22 June. The sun travels from Uttarayan to Dakshinayan on 21st June. According to religious beliefs, Dakshinayan is the night of Kal Devas. Nights and longer and days are shorter during Dakshinayan. During Dakshinayan, Sun travels with an inclination toward the southern direction.

Dakshinayan is the period associated with fasts. Many kinds of auspicious works are prohibited during Dakshinayan. This period is auspicious for Tamsik activities.
