repeating-interval

A simple library for parsing and interpreting ISO 8601 repeating time intervals.

The library also has the ability to handle non repeating intervals.

Installation

npm install repeating-interval --save

Usage

import {Interval} from 'repeating-interval';

let interval = new Interval('R/2016-08-23T04:00:00Z/P1D');

Examples of ISO 8601 repeating intervals

ISO 8601 repeating intervals are of the form: R<number of repetitions>/<ISO 8601 duration>

If the number of repititions is omitted then the interval repeats indefinitely. eg. R/2016-08-23T04:00:00Z/P1D would occur every one day at 4am UTC starting on the 23rd of August.

It is also possible to recur into the past by putting the duration (P1D) before the time (2016-08-23T04:00:00Z) eg. R/P1D/2016-08-23T04:00:00Z would occur every day before the 23rd of August, with the last occurance being at 4am UTC on the 23rd of August.
