In the Jain idea of time the smallest division is called a "samaya", and it is so small that there are innumerable "samayas" in a wink of the eye, etc., which is called an "avali". Sixteen million, seven hundred and seventy-seven thousand, two hundred and sixteen "avails" make 48 minutes, or one "muhurta".
Thirty muhurtas make one day.
Fifteen days make one fortnight.
Two fortnights one month.
Twelve months one year.
Innumerable years make one "palyopama".
1,000,000,000,000,000 palyopamas make one sagaropama. In India five sorts of years are recognized, viz. solar, lunar, seasonal, and two others. The seasonal year is of 360 days.
