Notes: All timings are represented in 12-hour notation in local time of Fairfield, United States with DST adjustment (if applicable).
Hours which are past midnight are suffixed with next day date. In Panchang day starts and ends with sunrise.
In Vedic astrology, a day spans from sunrise to next day sunrise. In other words, day begins with sunrise and ends with next day sunrise. The time between Sunrise to Sunset is divided into 30 Ghati (a Vedic unit to measure time) and time between Sunset to Sunrise is also divided into 30 Ghati. That means a complete day consists of 60 Ghati(s), 30 during day time and 30 during the night time.
One complete day = 60 Ghati
1 Ghati = 60 Pala
1 Pala = 60 Vipala
1 Vipala = 60 Valipta
Ghati is a Vedic unit to measure time, which is still used in Vedic astrology. It is thirtieth (30th) part of a day. If we divide total time between sunrise to sunset by 30 we get a Ghati duration, which is approximately 24 minutes.
Many people confuse that Ghati time is fixed and 2.5 Ghati is equal to 1 hour. This assumption results in wrong calculations and wrong Muhurat time. Length of a Ghati (the time unit) is not fixed and it varies from day to day and place to place.
The duration between sunrise and sunset time = 30 Ghati
(The duration between sunrise and sunset time / 30) = 1 Ghati
There are 30 Muhurat (Muhurta) in whole day. 15 Muhurat during the day-time and 15 Muhurat during the night-time. Each Muhurat consists to two Ghati. In Hindi language "two" is translated into "दो" (Do). That is why these 30 Muhurats are known as Do Ghati Muhurat. The name of all 30 Muhurat is as follows -
