Nakshatra is one of 27 lunar mansions. The Moon spends about a day in each. Namkaran, some muhurats, and Panchaka (the last five mansions) use this name.
Like tithi, a nakshatra can change during the civil day. We print the name at sunrise and the end time. Do not copy a Mumbai end clock for Bikaner.
On Apna Panchang the day page and the homepage snapshot both show the sunrise nakshatra in Hindi when you read the site in Hindi.
