moment.js - test if a date is today, yesterday, within a week or two weeks ago

Question

I am trying with moment.js to know if a date is today, yesterday, 1 week ago, or older (2 weeks ago or more).

I already done that for the first two cases:

var today = moment().startOf('day'); var yesterday = moment().subtract(1, 'days').startOf('day');  if (moment(localTime).isSame(today, 'd')) // today     // do something if (moment(localTime).isSame(yesterday, 'd')) // yesterday     // do something 

Is that correct?

However, how could I check if a date is a week ago, or older (eg. two weeks ago)?

Here's something that can be useful:

var REFERENCE = moment("2015-06-05"); // fixed just for testing, use moment(); var TODAY = REFERENCE.clone().startOf('day'); var YESTERDAY = REFERENCE.clone().subtract(1, 'days').startOf('day'); var A_WEEK_OLD = REFERENCE.clone().subtract(7, 'days').startOf('day');  function isToday(momentDate) {     return momentDate.isSame(TODAY, 'd'); } function isYesterday(momentDate) {     return momentDate.isSame(YESTERDAY, 'd'); } function isWithinAWeek(momentDate) {     return momentDate.isAfter(A_WEEK_OLD); } function isTwoWeeksOrMore(momentDate) {     return !isWithinAWeek(momentDate); }  console.log("is it today? ..................Should be true: "+isToday(moment("2015-06-05"))); console.log("is it yesterday? ..............Should be true: "+isYesterday(moment("2015-06-04"))); console.log("is it within a week? ..........Should be true: "+isWithinAWeek(moment("2015-06-03"))); console.log("is it within a week? ..........Should be false: "+isWithinAWeek(moment("2015-05-29"))); console.log("is it two weeks older or more? Should be false: "+isTwoWeeksOrMore(moment("2015-05-30"))); console.log("is it two weeks older or more? Should be true: "+isTwoWeeksOrMore(moment("2015-05-29")));
