Choghadia (or muhurat) is a popular Indian system of finding the auspicious and inauspicious times of the day. These time units are calculated from sunrise to sunrise. It is considered lucky to start any new work during the auspicious time. The times can vary from city to city and the app takes that and the timezone (including Daylight sacing for USA) into consideration. It also shows the choghadia (or muhurat) at the current time of the day.
