Conversion Units

The units involved in this change are weeks and days. This is how they are defined:


A week (symbol: wk) is a unit of time of seven days. This is the standard period used for rest day cycles in most parts of the world, primarily in connection with, but not exclusively within, the Gregorian calendar. The days of the week were baptized after the classical planets (derived from the astrological system of planetary hours) in Roman times. In English the names are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.


A day (symbol: d) is a unit of time. In common parlance, it is a 24-hour, or day, interval, the consecutive length of time that the sun is above the horizon. The period of time that the earth revolves around the sun is called a solar day. Various definitions of this universal human concept are used depending on context, need, and convenience. In 1960, the second was redefined in relation to Earth’s orbit and designated the fundamental SI unit of time. The “day” unit of measure, redefined in 1960 as 86,400 SI seconds and symbolized as d, is not a SI unit but is accepted for use with SI. A calendar day is typically 86,400 seconds plus or minus a possible leap second in Coordinated Universal Time (UTC), and sometimes plus or minus an hour in places that are changing to or from Daylight Saving Time.
