Tithi (तिथिः) is a fundamental unit of lunar time (Chandra Mana) - the time taken for the movement of moon by 12 degrees as compared to the Sun. The moon, like the sun, moves from west to east with reference to the fixed stars. The motion of the Moon is much faster than that of the Sun. Moving at a small angle of 5° 8′ towards the ecliptic, the movement of the moon may be considered as moving along the ecliptic itself. Observations show that moon takes an average period of 27.3216615 days to complete a revolution of 360° with reference to the fixed stars, which is called the Sidereal period of the Moon. For the same angular movement of 360° along the ecliptic, in the same direction with reference to the fixed stars, the Sun takes about 365.256364 days, which is the Sidereal period (Year) of the Sun. Thus we have
