The moment of the new Moon, or that point of time when the longitudes of Sun and Moon are equal is called No moon. The lunar (tithi) is time taken by the Moon in increasing its distance from the Sun by 12 degrees. The complete revolution of the Moon (29.5 days) occupies 30 tithis for 360 degrees. Since the motions of the Sun and Moon are always varying in speed, the length of a tithi constantly alters. We calculate the tithis from 2,000 BC till 3,000 AD, we show that this method of calculating the constants from trigonometric formulae gives an accurate prediction around 500 AD when the tables were created. According to the Mayan calendar your original date of birth is calculated.
Lunar readings are calculated according to ancient Hindu calendar in which people see the phases of the Sun and the Moon. By the Lunar reading you can know your inner feelings, ideas, behaviours and purpose which is hard for you to share with anyone. Lunar is connected with your actual birth day.
Lunar will calculate how your mind runs, which things you shouldn't try and how you connect with people. So time of birth is also necessary to know about your lunar day.
