strftime support for Moment.js


Moment.js is a great, lightweight date-manipulation library, with a very approachable date format syntax that makes it a breeze to work with dates and times in the Javascript world.

Unfortunately, the library doesn't support (and won't do it) one of the most common approaches to format strings: the Unix-Style strftime syntax.

This plugin (any many others) aims to fill the gap.

Installation (NPM)

Simply do:

npm install moment-strftime2

Installation (Bower)

Simply do:

bower install moment-strftime2


const moment = require("moment");

moment().strftime("%m/%d/%y %I:%M %p %Z"); // => "16/09/11 09:22 AM CET"

Supported modifiers

This plugin supports all modifiers listed here with the exception of the following:

  • %c
  • %C
  • %E
  • %G
  • %n
  • %O
  • %t
  • %U
  • %x
  • %X
  • %+

And with the addition of the following modifiers:

  • %L: The milliseconds as decimal-number (range 000 to 999).


You can completely customize moment-strftime2 behavior by requiring the module and overriding the separator and modifiers variables:


const moment = require("moment");
const strftime2 = require("moment-strftime2");

moment("2016-10-10 12:34:56.135 +02:00").strftime("%d %o #d #o"); // "10 %o #d #o"
strftime2.separator = "$"
strftime2.modifier.o = "DD";
moment("2016-10-10 12:34:56.135 +02:00").strftime("%d %o #d #o"); // "%d %o 10 10"

Supported implementations.

moment-strftime2 supports and has been tested on NodeJS 6.0+.
