About these units
Years (y)
This converter uses the Julian year of 365.25 days, the astronomers’ standard. A calendar year is 365 days, with a leap day roughly every four years.
Days (d)
A day is 86,400 seconds. The Earth actually turns slightly faster or slower, so leap seconds are occasionally added to keep clocks in step.
