Year / Day Units Definition
Year
The annum (“year” in Latin), with symbol a, is a non-SI unit of time measurement, worth one Julian year, or exactly 365.25 days or 31,557,600 seconds.
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.
