The synthesis of the Puranas and the Siddhantas (Mythology or Science)

Hare Krishna Adbhut Hari prabhu,

In relation to what you mentioned regarding “the duration of day on moon planet”, below are the details from Surya Siddantha and Srimad Bhagavatham to understand how one month on our planet is equivalent one day on Moon.

On an average, in a period of 4320000 solar years (chaturyuga) there are 1577917828 risings of Sun and 1524484492 risings of the moon on our planet (Surya Sidd 1.34). In other words, on our planet there are approximately 365.2587565 risings of Sun and 352.8899287 risings of the moon in a year. Now, let us calculate how many risings of sun will happen on the moon planet during a period of a chaturyuga. It will be equal to Number of risings of Sun on our planet in a chaturyuga – Number of risings of Moon on our planet in a chaturyuga = 1524484492 – 1577917828 = 53433336. This number is approximately 30 times smaller than the number of risings of Sun on our planet in a chaturyuga. Stated differently, there are only 12.36882778 risings of Sun on the moon planet, for every 365.2587565 risings of Sun on our planet. If we define a complete day on the planet to be duration of time between one sun rise to next sun rise, the duration of one complete day on moon planet is equivalent to (Number of Risings of Sun in a year on our planet)/(Number of Risings of Sun in a year on the moon planet) = 365.2587565/12.36882778 = 29.53058795 earthly days. These calculations from first chapter of Surya Siddhanta explain how approximately one month on our planet is equivalent to one complete day on the moon planet. This is confirmed in Surya Siddhanta 12.74. In Matsya Purana, chapter OXLI, verses 26-28 it is stated that the phases of the Moon that wax in course of the bright fortnight fed by Susumna rays of Sun, wane during the dark fortnight. In this way the Moon continues to wax and wane, consequently, the full-moon is called the receptacle of nectar. He is luminous with the fifteen nectar-giving phases. Moon is, therefore, called Pitriman. In reference to Pirtloka, it is explained in Srimad Bhagavatam 5.22.5 that according to lunar calculations, two fortnights—one of the waxing moon and the other of the waning—form one month. That same period is one day and night for the planet Pitrloka.

Hopefully this will be of some help in understanding the relativity of time between earth and the moon.

Your servant,
Ravi Kumar.
