In Sanskrit, Samay (समय) is the, "appointed or proper time, [the] right moment for doing anything." On a general parlance, samay is a unit of time. The samay chakra is the great chariot wheel of time which turns relentlessly forward.
Samay represents the most infinitesimal part of time that cannot be divided further. The blink of an eye, or about a quarter of a second, has innumerable samay in it. For all practical purposes a second happens to be the finest measurement of time. Jainism however, recognizes a very small measurement of time known as samay, which is an infinitely small part of a second.
The following are measurements of time as adopted by Jainism: Indivisible time = 1 samay
Innumerable samay = 1 avalik
16,777,216 avalik = 1 Muhurt
30 Muhurtas = 1 Day and night
15 Days and nights = 1 Paksha (fortnight )
2 Pakshas = 1 Month
12 Months = 1 Year
Innumerable years = 1 Palyopam
10 millions of millions of Palyopams = 1 Sāgaropam
10 million of millions of Sāgaropams = l Utsarpini or 1 Avasarpini
1 Utsarpini + Avasarpini = 1 Kālchakra (One time cycle).
Samay was the basic unit of time in ancient Hindu mythology. Currently, it is used synonymously with time.
Samay in music
In Gandharva-Veda the day is divided into three-hour-long intervals: 4-7 a.m., 7-10 a.m. etc. The time concept in Gandharva-Veda is more strictly adhered to than it would be, for example, in Carnatic music.
