A Moment.js plugin for getting the weekdays of a month, year, or inbetween two dates.

Examples

weekdaysInBetween(date, weekdays, index)

// All weekends in the summer of 2010
var summerWeekends = moment('2010-06-20').weekdaysInBetween('2010-09-23', [0, 5, 6]);

// Mondays remaining this year
var remainingMondays = moment().weekdaysInBetween(moment().endOf('year'), 'Monday');

// Last Wednesday
var lastWednesday = moment().dayOfYear(1).weekdaysInBetween(null, 3, -1);

// Second to last Friday before Christmas
var paydayBeforeChristmas = moment().weekdaysInBetween(moment().month('December').date(25), 'Friday', -2);

weekdaysInMonth(weekdays, index)

// Holidays this year
var memorialDay = moment().month('May').weekdaysInMonth('Monday', -1);
var laborDay = moment().month('September').weekdaysInMonth('Monday', 1);
var thanksgivingDay = moment().month('November').weekdaysInMonth('Thursday', 4);

// Wednesdays in May of 1995
var mayWednesdays = moment('1999-05-01').weekdaysInMonth(3);

weekdaysInYear(weekdays, index)

// Last two weekends of the year
var lastWeekendsOfYear = moment().weekdaysInYear([0, 5, 6], [-1, -2]);

// Thursdays this year
var thursdaysThisYear = moment().weekdaysInYear('Thursday');

// The 10th and 4th to last Sundays and Wednesdays this year
var complicatedExample = moment().weekdaysInYear(['Sunday', 3], [10, -4]);

Parameters

• date (weekdaysInBetween only) - The end date for weekdaysInBetween. Can be any ISO date string that moment accepts or a moment object. Defaults to today.
• weekdays - The weekdays to fetch. Can be any value that moment().day() accepts or an array of those values. Defaults to all.
• index - The index of the days to fetch. 1-indexed based. Can be a negative number. 1 will get the first instance, -1 will get the last. Can be a single value or an array of values. Defaults to all.

All parameters are optional.

Things To Note

All three functions will:

• Return a sorted array of moment objects if there are multiple found.
• Return a single moment object if there is only one found.
• Return false if none are found.
• Never return duplicate moment objects.

That means something like this may be necessary:

var t = moment().weekdaysInBetween(moment().endOf('year'), 'Monday');

if (t) {
  if (t.length) {
    // Returned multiple
  } else {
    // Returned one
  }
} else {
  // Returned none
}

However if weekdays and index parameters are both set to single values, you will never get multiple values returned.
