Frequently asked questions
How many seconds are in an hour?
There are 3,600 seconds in an hour: 60 seconds times 60 minutes. A full day holds 86,400 seconds.
How many days are in a year here?
UnitGlide uses the average year of 365.25 days, which accounts for leap years. That is why a year is stored as 31,557,600 seconds rather than exactly 365 days.

A month is treated as one twelfth of the average year, about 30.44 days. Calendar months vary from 28 to 31 days, so use this as an approximation.
