34000TH OF A SECOND TO 4.32 BILLION YEARS
India has given the world the idea of the smallest and the largest
measurement of time ever.

Krati Krati = 34,000th of a second

1 Truti = 300th of a second

2 Truti = 1 Luv

2 Luv = 1 Kshana

30 Kshana = 1 Vipal

60 Vipal = 1 Pal

60 Pal = 1 Ghadi (24 minutes)

2.5 Gadhi = 1 Hora (1 hour)

24 Hora = 1 Divas (1 day)
7 Divas = 1 saptaah (1 week)

4 Saptaah = 1 Maas (1 month)

2 Maas = 1 Rutu (1 season)

6 Rutu = 1 Varsh (1 year)

100 Varsh = 1 Shataabda (1 century)

10 Shataabda = 1 sahasraabda

432 Sahasraabda = 1 Yug (Kaliyug)

2 Yug = 1 Dwaaparyug

3 Yug = 1 Tretaayug

4 Yug = 1 Krutayug

10 Yug = 1 Mahaayug (4,320,000 years)

1000 Mahaayug = 1 Kalpa
1 Kalpa = 4.32 billion years

In Surya Siddhanta, Bhaskaracharya calculates the time taken for the
earth to orbit the sun to 9 decimal places.
Bhaskaracharya = 365.258756484 days.

Modern accepted measurement = 365.2596 days.

Between Bhaskaracharya's ancient measurement 1500 years ago and the
modern measurement the difference is only 0.00085 days, only 0.0002%.
