date-period Build status

Time period iterator.

A time period in this context is an array of Date objects, recurring at regular intervals, over a given period. Based on ISO 8601's duration and repeating interval format.

Mimics PHP's excellent DatePeriod class.

Installation

$ npm install date-period --save

Use

API

Start, duration and end date:

createPeriod({ start: Date, duration: String, end: Date }) ⇒ Array<Date>

Start, duration, and number of recurrences:

createPeriod({ start: Date, duration: String, recurrence: Number }) ⇒ Array<Date>

ISO 8601 Repeating time intervals:

createPeriod({ iso: String }) ⇒ Array<Date>

The date and duration parameters can be objects which have, respectively, toDate and toString methods. This way moment objects are supported.

Example

Require the module

const createPeriod = require('date-period');

Define a period

let start = new Date('2014-01-01T00:00:00Z'),
    duration = 'P1D',
    end = new Date('2014-01-05T00:00:00Z'), // not included in result
    period;
 
period = createPeriod({ start, duration, end });
 
// or, with the number of recurrences instead of an end date:
period = createPeriod({ start, duration, recurrence: 3 });
 
// or, with a string formatted as an ISO 8601 repeating interval:
period = createPeriod({ iso: 'R3/2014-01-01T00:00:00Z/P1D' });

Install

npm i date-period
