I need a function to return the specific date for a given holiday name as input -:)
Nice! Thanks!
I love it ! :)
It looks like we won't be able to use the format on the example near future - moment('12/25/2013'). It still works but it gets warning. I just squeezed non-format date instead and it works without a warning message.

It appears there's also a bug in this code that excludes both the 4th and the 5th Monday when May starts on a Saturday (e.g. 2021-05).
Github fooled me and made me think I'd posted my first comment twice. Deleting one of the "copies" deleted the actual comment. Here's a loose reconstruction:
Thanksgiving Day and the Day after Thanksgiving don't fall on numerically consistent dates. Thanksgiving is always on the fourth Thursday in November. Their expression in the 'M' sub-hash above will only appear correct 2 out of every 14 years. They're wrong for 2016.
Memorial Day is the last Monday in May, not necessarily the 5th Monday. Whenever May starts on a Tuesday, Wednesday, Thursday, or Friday, Memorial Day will fall on the 4th Monday of the month. Being able to express a "last" n-day of the month would be useful and would fix this problem, e.g. '5/-1/1'.
We tested with this service(https://www.timeanddate.com/holidays/us/2017#!hol=9) for few years ahead and it seems to be fixed.
if anyone want to use it as a function
function checkIsHoliday(date) {
var _holidays = {
'M': {//Month, Day
'01/01': "New Year's Day",
'07/04': "Independence Day",
'11/11': "Veteran's Day",
'11/28': "Thanksgiving Day",
'11/29': "Day after Thanksgiving",
'12/24': "Christmas Eve",
'12/25': "Christmas Day",
'12/31': "New Year's Eve"
},
'W': {//Month, Week of Month, Day of Week
'1/3/1': "Martin Luther King Jr. Day",
'2/3/1': "Washington's Birthday",
'5/5/1': "Memorial Day",
'9/1/1': "Labor Day",
'10/2/1': "Columbus Day",
'11/4/4': "Thanksgiving Day"
}
};
var diff = 1+ (0 | (new Date(date).getDate() - 1) / 7);
var memorial = (new Date(date).getDay() === 1 && (new Date(date).getDate() + 7) > 30) ? "5" : null;
return (_holidays['M'][moment(date).format('MM/DD')] || _holidays['W'][moment(date).format('M/'+ (memorial || diff) +'/d')]);
}

@jrhames The thanksgiving day appears both in 'M' and 'W' hashes. Is this correct? https://gist.github.com/jrhames/5200024#file-moment-holidays-js-L28
I've created a plugin for moment that takes care of all your holiday handling and calculating needs: https://github.com/kodie/moment-holiday
My isHoliday()
function accomplishes exactly what @jrhames's gist was attempting to do accurately (@baburdick pointed out that this gist doesn't accurately figure out when Thanksgiving or Memorial day is)
For example:
moment('2017-12-25').isHoliday();
//Christmas Day
Also, my holiday()
function does exactly what @ihomecall was needing.
For example:
moment().holiday('Memorial Day');
//moment("2017-05-29T00:00:00.000")
Let me know what you think!
I want to get the full list of the national holidays (names) how can I use this?
@kodie, I tried to use your plugin on my Angular 2 app and I couldn’t get it to work. Any idea why? I got it to work on my Hugo project and it’s great!
Thank you my friend :) Very useful
