The lunar day, and the minute it ends. A tithi is the 12° the Moon gains on the Sun. It does not run midnight to midnight, and it is never the same length twice.

A tithi is the time the Moon takes to move 12° further ahead of the Sun. Thirty of them make one lunar month: fifteen in the waxing Shukla paksha, ending at Purnima, and fifteen in the waning Krishna paksha, ending at Amavasya. Because the Moon does not move at a constant speed, a tithi can run from about 20 to about 27 hours.
