0.01 d (1 % of a day) 14.4 minutes, or 864 seconds. One-hundredth of a day is 1 cd (centiday), also called "kè" in tradidional Chinese timekeeping. The unit was also proposed by Lagrange and endorsed by Rey-Pailhade [5] in the 19th century, named "centijours" (from French centi-'hundred' and jour 'day'). kilosecond: 10 3 s: About 17 minutes ...

A Gregorian year, which takes into account the 100 vs. 400 leap year exception rule of the Gregorian calendar, is 365.2425 days (the average length of a year over a 400–year cycle), resulting in 0.1 years being a period of 36.52425 days (3 155 695.2 seconds; 36 days, 12 hours, 34 minutes, 55.2 seconds).
Measuring a day as such is used in astronomy. [6] A sidereal day is about 4 minutes less than a solar day of 24 hours (23 hours 56 minutes and 4.09 seconds), or 0.99726968 of a solar day of 24 hours. [7] There are about 366.2422 stellar days in one mean tropical year (one stellar day more than the number of solar days). [8]

Hexadecimal time is the representation of the time of day as a hexadecimal number in the interval [0, 1). The day is divided into 10 16 (16 10 ) hexadecimal hours, each hour into 100 16 (256 10 ) hexadecimal minutes, and each minute into 10 16 (16 10 ) hexadecimal seconds.
For medieval commoners the main marker of the passage of time was the call to prayer at intervals throughout the day. The earliest reference found to the moment is from the 8th century writings of the Venerable Bede, [5] who describes the system as 1 solar hour = 4 puncta = 5 lunar puncta [6] [7] = 10 minuta = 15 partes = 40 momenta.
