C# DateTime.MaxValue equivalent in javascript

Question

Is there any way to get the same value of date time in javascript that c# DateTime.MaxValue returns?

Answer 1

Well, yes. The max date in .NET is 23:59:59.9999999 UTC, December 31, 9999. So this would be the equivalent Javascript:

var d = new Date(9999, 12, 31, 23, 59, 59, 9999999);

There is no Date.MaxValue in Javascript, so you have to make it your own.

Answer 2

The above edge case as mentioned by James Thorpe can be avoided by using:

    public dateTimeMax = new Date(9999, 11, 31, 23, 59, 59, 999);

This is because the month is zero-indexed, and the highest value it can take for milliseconds is 999.
