The Hindu day: from sunrise to sunrise
Unlike the civil day, which turns at midnight, the Hindu day begins at sunrise and runs to the next sunrise. The weekday and the tithi that name a day are the ones in force at sunrise at your place.
So a limb can change at any hour: a tithi might begin at 3 in the afternoon and end at 1 the next afternoon. Stella’s Panchang lists every limb that touches the day, each with its start and end to the second, together with sunrise, sunset, moonrise and moonset.
