Simple JavaScript API : Countdown JS

Countdown.js  – A simple JavaScript API for producing an accurate, intuitive description of the timespan between two Date instances.

The library calculates the value continuously considering “the time goes on” and keeps generating an accurate output. It can provide the timespan in many formats like milliseconds, seconds, minutes, hours, days, weeks and even millennias.

There are methods for displaying it as an English sentence like “3 years, 6 months, 21 days, 10 hours, and 32 minutes”.

The countdown can be reset easily and there are callbacks both on

start

and

end
