The unit of measurement "day" is defined as 86,400 SI seconds and symbolized d. A day is usually 24 hours, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.


A decade is a period of 10 years. Decades may describe any ten-year period, such as those of a person's life, or refer to specific groupings of calendar years.
