When using Moment.js to get the end of a day, it returns 22:59:59.999Z:

moment('2013-W06-5').endOf('day') // 2013-02-08T22:59:59.999Z

See .

Can anyone please explain why the day doesn't end at 23:59:59.999Z?

I don't think Moment.js handles it wrong. Maybe it's something about daylight saving time (writing from German)?

• From the docs, endOf set the moment to 23:59:59.999, I don't think it is a bug, probably something in your code, you need to share it to let us help you further. – VincenzoC Commented Jun 1, 2017 at 13:58
• I don't think its a bug either. Added source code and link to Plunker to original post. – Sommereder Commented Jun 1, 2017 at 15:00
• The issue is the way you are showing the value inside your angular view. Convert moment object to string using format() in your controller or use angular-moment inside your view. – VincenzoC Commented Jun 1, 2017 at 15:05

endOf is timezone aware.

Use .utc() and you get what you need:

$scope.output = moment('2013-W06-5').utc().endOf('day');
=> "2013-02-08T23:59:59.999Z"
