Waheguru Ji Ka Khalsa, Waheguru Ji Ki Fateh
In a post, by someone else on another site, the reference to the calculation of time in Sri Guru Granth Sahib Ji is quoted to be;
ਅੱਖ ਦੇ ੧੫ ਫੋਰ = ੧ ਵਿਸਾ।
15 blinks of eye= 1 Vissa;
੧੫ ਵਿਸੁਏ = ੧ ਚਸਾ।
15 Vissas’= 1 Chassa;
੩੦ ਚਸੇ = ੧ ਪਲ।
30 chassas’= 1 Pal;
੬੦ ਪਲ = ੧ ਘੜੀ।
60 pals’= 1 karih;
ਸਾਢੋ ੭ ਘੜੀਆਂ = ੧ ਪਹਰ।
7 and half karih's= 1 pehar;
੮ ਪਹਰ = ੧ ਦਿਨ ਰਾਤ।
8 pehar's= 24 hours [day/night].
੧੫ ਥਿਤਾਂ; ੭ ਵਾਰ; ੧੨ ਮਹੀਨੇ, ਛੇ ਰੁੱਤਾਂ।
There were 15 Tithis’ = days of lunar month; 7 vaars= days of the week, 12 months and 6 seasons
Please can anyone confirm or refute this (with any supporting sources)?
