In vedic timekeeping, a tithi (also spelled thithi) is a lunar day, or the time it takes for the longitudinal angle between the moon and the sun to increase by 12°. Tithis begin at varying times of day and vary in duration from approximately 19 to approximately 26 hours.
There are 30 tithis in each lunar month, named as follows:
| Krsna paksa (dark fortnight) | Gaura paksa (bright fortnight) | |
|---|---|---|
| 1 | Pratipat | Pratipat |
| 2 | Dvitiya | Dvitiya |
| 3 | Trtiya | Trtiya |
| 4 | Caturthi | Caturthi |
| 5 | Pancami | Pancami |
| 6 | Sasti | Sasti |
| 7 | Saptami | Saptami |
| 8 | Astami | Astami |
| 9 | Navami | Navami |
| 10 | Dasami | Dasami |
| 11 | Ekadasi | Ekadasi |
| 12 | Dvadasi | Dvadasi |
| 13 | Trayodasi | Trayodasi |
| 14 | Caturdasi | Caturdasi |
| 15 | Amavasya (new moon) | Purnima (full moon) |
Ekadasi, the eleventh day of each lunar fortnight, has special religious significance in Hinduism and Jainism -- usually observed by fasting.pl:Tithi
