Check out all their awesome documentation  Here is where they discuss the Warning Message  String   Format  Warning  Browser support for parsing strings is inconsistent  Because there is no specification on which formats should be supported  what works in some browsers will not work in other browsers  For consistent results parsing anything other than ISO 8601 strings  you should use String   Format   moment  quot 12-25-1995 quot    quot MM-DD-YYYY quot     String   Formats  multiple formats  If you have more than one format  check out their String   Formats  with an  s     If you don t know the exact format of an input string  but know it could be one of many  you can use an array of formats   moment  quot 12-25-1995 quot     quot MM-DD-YYYY quot    quot YYYY-MM-DD quot      Please checkout the documentation for anything more specific  Timezone Checkout Parsing in Zone  the equivalent documentation for timezones   The moment tz constructor takes all the same arguments as the moment constructor  but uses the last argument as a time zone identifier   var b   moment tz  quot May 12th 2014 8PM quot    quot MMM Do YYYY hA quot    quot America Toronto quot     EDIT       var dateFormat    quot YYYY-M-D H m quot      lt -------- This part will get rid of the warning  var aus1 s  aus2 s  aus3 s  aus4 s  aus5 s  aus6 s  aus6 e  if     quot  custom1  selected quot   val       quot AU quot          var region    Australia Sydney        aus1 s   moment tz  2016-9-26 19 30   dateFormat  region                     aus2 s   moment tz  2016-10-2 19 30   dateFormat  region                     aus3 s   moment tz  2016-10-9 19 30   dateFormat  region                         aus4 s   moment tz  2016-10-16 19 30   dateFormat  region                        aus5 s   moment tz  2016-10-23 19 30   dateFormat  region       aus6 s   moment tz  2016-10-30 19 30   dateFormat  region       aus6 e   moment tz  2016-11-5 19 30   dateFormat  region     else if     quot  custom1  selected quot   val       quot NZ quot          var region    Pacific Auckland        aus1 s    moment tz  2016-9-28 20 30   dateFormat  region       aus2 s    moment tz  2016-10-4 20 30   dateFormat  region       aus3 s    moment tz  2016-10-11 20 30   dateFormat  region       aus4 s    moment tz  2016-10-18 20 30   dateFormat  region       aus5 s    moment tz  2016-10-25 20 30   dateFormat  region       aus6 s    moment tz  2016-11-2 20 30   dateFormat  region       aus6 e    moment tz  2016-11-9 20 30   dateFormat  region

This answer is to give a better understanding of this warning  Deprecation warning is caused when you use moment to create time object  var today   moment      If this warning is okay with you then I have a simpler method   Don t use date object from js use moment instead  For example use moment   to get the current date   Or convert the js date object to moment date  You can simply do that specifying the format of your js date object    ie  moment  js date    js date format     eg   moment  2014 04 25    YYYY MM DD       BUT YOU CAN ONLY USE THIS METHOD UNTIL IT S DEPRECIATED  this may be depreciated from moment in the future

I ran into this error because I was trying to pass in a date from localStorage  Passing the date into a new Date object  and then calling  toISOString   did the trick for me   const dateFromStorage   localStorage getItem  someDate    const date   new Date dateFromStorage   const momentDate   moment date toISOString       This suppressed any warnings in the console
