Why does a tithi change during the day?
Tithis are defined by the Sun-Moon angle, not the clock, so they begin and end at any time of day and last between about 19 and 26 hours. The tithi at sunrise (udaya tithi) is usually the one used for the day's observance.
How are these times calculated?
From real Sun and Moon positions (NASA JPL DE421 ephemeris). All times are Indian Standard Time (UTC+5:30).
