Quick answers.

How many seconds are in a day?

86,400 seconds — that's 60 (sec/min) × 60 (min/hr) × 24 (hr/day).

How long is a 'month'?

We use the average of 30.44 days (365.25 ÷ 12) so the math is consistent. A real month is 28-31 days.

What about leap years?

We use 365.25 days as the average year length, which accounts for leap years over a 4-year cycle.

How do I convert milliseconds to seconds?

Divide by 1,000. So 5,000 ms = 5 s. Or type your value and pick the units.
