calendar-month-array

calendar-month-array

Generates a calendar array with the days of a single month, organized by week.

This is a fork of module calendar-month-string by Substack. The goal is to return a basic date array in place of a formatted string.

example

var calendar = require('calendar-month-array')
var weeks = calendar()
console.log(weeks)

output:

[ [ 2017-05-27T22:00:00.109Z,
    2017-05-28T22:00:00.109Z,
    2017-05-29T22:00:00.109Z,
    2017-05-30T22:00:00.109Z,
    2017-05-31T22:00:00.109Z,
    2017-06-01T22:00:00.109Z,
    2017-06-02T22:00:00.109Z ],
  [ 2017-06-03T22:00:00.109Z,
    2017-06-04T22:00:00.109Z,
    ...

NOTE: event if you can't see it on the console, they are Date objects, not ISO date strings!

With some formatting and optional headers:

var sprintf = require('sprintf')
var weeks = calendar(new Date(2017, 5), { 
  weekStartDay: 1,
  formatHeader: date => date.toString().slice(0, 2),
  formatDate: date => sprintf('%2d', date.getDate()),
  formatSiblingMonthDate: () => '  '
})
console.log(weeks)

output:

[ [ 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa', 'Su' ],
  [ '  ', '  ', '  ', ' 1', ' 2', ' 3', ' 4' ],
  [ ' 5', ' 6', ' 7', ' 8', ' 9', '10', '11' ],
  [ '12', '13', '14', '15', '16', '17', '18' ],
  [ '19', '20', '21', '22', '23', '24', '25' ],
  [ '26', '27', '28', '29', '30', '  ', '  ' ] ]
