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 dates arrays in place of a formatted string.

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: these areDateobjects, 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', '  ', '  ' ] ]

var calendar = require('calendar-month-array')

var weeks = calendar(date, opts)

Return an array of weeks weeks for the month given in date, a Date instance.

• opts.weekStartDay - set the first day of week, default 0 (Sunday). Monday would be 1.
• opts.formatDate(currentDate, info) - specify how to format each cell, default is returning Date object.

currentDate - the date object. info - some details about the date.

* `info.dayOfMonth` - the relative day in the month.
* `info.siblingMonth` - the month offset, `-1` for previous, `0` is current, `1` is next.
* `info.week` - week index, starting at 0 for first week presented.
* `info.position` - day index, or position in week, startting at 0.

• opts.formatSiblingMonthDate(currentDate, info) - define how to format cells for sibling month, default to opts.formatDate.
• opts.formatHeader(currentDate, position) - define how to format an optional header row (added only if opts.formatHeader is defined)

currentDate - date object, just to know the day of week. position - position in week.BSD
