AM/PM1.6.0+

  1. // From 2.12.0 onward
  2. moment.updateLocale('en', {
  3.     meridiem : Function
  4. });
  5. // From 2.8.1 to 2.11.2
  6. moment.locale('en', {
  7.     meridiem : Function
  8. });
  10. // Deprecated in 2.8.1
  11. moment.lang('en', {
  12.     meridiem : Function
  13. });

If your locale uses 'am/pm', Locale#meridiem can be omitted, as those values are the defaults.

If your locale needs any different computation for am/pm, Locale#meridiem should be a callback function that returns the correct string based on hour, minute, and upper/lowercase.

  1. moment.updateLocale('zh-cn', {
  2.     meridiem : function (hour, minute, isLowercase) {
  3.         if (hour < 9) {
  4.             return "早上";
  5.         } else if (hour < 11 && minute < 30) {
  6.             return "上午";
  7.         } else if (hour < 13 && minute < 30) {
  8.             return "中午";
  9.         } else if (hour < 18) {
  10.             return "下午";
  11.         } else {
  12.             return "晚上";
  13.         }
  14.     }
  15. });
