## Conversion Units

The units involved in this conversion are months and days. This is how they are defined:

### Month

A month (symbol: mo) is a unit of time used in calendars, approximately the same length as a natural period related to the moon’s movement; the month and the moon are related. The traditional concept arose with the moon’s phase cycle; these months (lunations) are synodic and last about 29.53 days. From unearthed counting sticks, researchers have concluded that humans have been counting days about the moon’s phases since the Paleolithic period. Synodic months, based on the orbital period of the moon relative to the earth-sun line, still form the basis of many calendars today and are used to divide the year.

### Day

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 that the Earth revolves around the sun is called a solar day. Various definitions of this universal human concept depend 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 changing to or from Daylight Saving Time.
