Knowing how ancient Indians calculated time will amaze their understanding of complex topics and how they went on to compose measurement units without modern day equipment, we all should be proud to be part of this rich heritage.
Sunrise to sunset and dusk to dawn everything and anything man does is related to time. Sun and the moon are the eternal sources to calculate time.
Our ancestors could calculate the time to as minute as 1 Krati = 1/34,000 second.
Let us see starting from a day how they have calculated time from maximum to minimum.
1 Truti = 0.031 µs
1 Renu = 60 Truti
1 Lava = 60 Renu
1 Lisaka = 60 Lava
1 Lipta = 60 Lisaka
1 Vigadiya = 60 Lipta
1 Ghadiya = 60 Vigadiya (24 Minutes)
1 Muhurtham = 2 Ghadiyalu (48 Minutes)
1 Aaho + 1 Rathri = 30 Muhurthalu
1 Day = 1 Aaho – 1 Rathri
1 Week = 7 Days (Monday, Tuesday…)
1 Paksham = 15 Days (Amavasya, Padyami, Vidhiya…..)
1 Masam = 2 Pakshalu (1 Krushna – 1 Shukla)
1 Ruthuvu = 2 Masalu (Chaithram, Vaishakam………)
1 Aayanam = 3 Ruthuvulu
1 Year = 2 Aayanas / 6 Ruthus / 12 Masam (For every 4 Years there will be one additional month called as “ADHIKA MASAM”. 6 Ruthuvs (Vasantham, Grishmama…….).(60 years each have a name starting from Prabhava, Vibhava….., 1 Pushkara = 12 Years. 1 Maha Pushkara = 12 Pushkaras)
1 Yugam = 4,320,000 Years|| (Kali Yuga X 2 = Dvapara Yuga, Kali Yuga X 3 = Treta Yuga, Kali Yuga X 4 = Krita Yuga)
1 Chaturyugam / 1 Maha Yugam = 4 Yugas (Krita, Treta, Dvapara, Kali Yuga)
1 Manvantara = 71 Chaturyugams / 71 Maha Yugas (306,720,000 Years)
1 Kalpa = 14 Manvantara (14 Manvantara have names) (30 Kalpa Shweta, Neelalohita……..)
1 Brahma day = 2 Kalpa
1 Brahma Masam = 30 Brahma Days
1 Brahma Year = 12 Brahma Masams
1 Padhardha = 50 Brahma Years
1 Brahma Kalam = 2 Padhardhams
When we convert these into present time units, we would be shocked.
1 Brahma day is divided into 1000 parts called as Charanas.
Present day we are in Kali Yuga, Prathama Pada (First), Shwetavaraha Kalpa, and Vaivaswatha Manvantara. When we visit a temple or perform a puja at home, priest utters these present time periods while performing Pooja, uttering them is a must.
We still do not know using what devices our ancestors calculated these time units and their use in which part of science is still a mystery to be solved, these units are mentioned in Puranas, Vedas, and Upanishads. Naming each of them and most of them is used some or the other time by us with the same name just makes us wonder of the capabilities of these men.
