Day / Month Units Definition
Day
The day is also a unit of time which, although outside the International System (SI), is in use with it. It is worth exactly 86,400 seconds and its symbol is “d” (from the Latin dies, but also the initial of the English word day). The French abbreviation “j” is nevertheless frequently used.
Month
A month corresponds to 1/12 of a year. A month is considered to correspond to approximately 4 weeks or 30 or 31 days. A day corresponds to the time it takes for the Earth to rotate on its axis, that is to say 24 hours.
