Just crop the string   var date   new Date  2013-03-10T02 00 00Z    date toISOString   substring 0  10     Or if you need only date out of string   var strDate    2013-03-10T02 00 00Z   strDate substring 0  10

Moment js will handle date formatting for you  Here is how to include it via a JavaScript tag  and then an example of how to use Moment js to format a date    lt script src  quot https   cdnjs cloudflare com ajax libs moment js 2 14 1 moment min js quot  gt  lt  script gt   moment  quot 2013-03-10T02 00 00Z quot   format  quot YYYY-MM-DD quot       quot 2013-03-10 quot

To extend on rk rk s solution  In case you want the format to include the time  you can add the toTimeString   to your string  and then strip the GMT part  as follows   var d   new Date  2013-03-10T02 00 00Z    var fd   d toLocaleDateString           d toTimeString   substring 0  d toTimeString   indexOf  GMT

Moment js is pretty big library to use for a single use case  I recommend using date-fns instead  It offers basically the most functionality of Moment js with a much smaller bundle size and many formatting options   import format from  date-fns format  format  2013-03-10T02 00 00Z    YYYY-MM-DD       2013-03-10  YYYY-MM-dd for 2 x   One thing to note is that  since it s the ISO nbsp 8601 time format  the browser generally converts from UTC time to local timezone  Though this is simple use case where you can probably do  2013-03-10T02 00 00Z  substring 0  10     For more complex conversions date-fns is the way to go

A better version of answer by  Hozefa   If you have date-fns installed  you could use formatISO function  const date   new Date 2019  0  2  import   formatISO   from  date-fns  formatISO date    representation   date         2019-01-02  string

To all who are using split  slice and other string-based attempts to obtain the date  you might set yourself up for timezone related fails   An ISO-String has Zulu-Timezone and a date according to this timezone  which means  it might use a date a day prior or later to the actual timezone  which you have to take into account in your transformation chain   See this example   const timeZoneRelatedDate   new Date 2020  0  14  0  0    console log timeZoneRelatedDate toLocaleDateString       ja-JP                year   numeric         month   2-digit         day   2-digit          replace     gi  -         RESULT   2020-01-14   console log timeZoneRelatedDate toISOString         RESULT   2020-01-13T23 00 00 000Z   for me in UTC 1   console log timeZoneRelatedDate toISOString   slice 0 10        RESULT   2020-01-13

You could checkout Moment js  Luxon  date-fns or Day js for nice date manipulation   Or just extract the first part of your ISO string  it already contains what you want   Here is an example by splitting on the T    2013-03-10T02 00 00Z  split  T   0      2013-03-10
