What is the earliest date an html date input can go? <p>In C# you can do <a href="https://msdn.microsoft.com/en-us/library/system.datetime.minvalue%28v=vs.110%29.aspx?f=255&amp;MSPPError=-2147217396" rel="nofollow">DateTime.MinValue</a>, but is there any method for this in JavaScript or HTML?</p> <p>I am aware of <code>Date(-number)</code> in JavaScript, but the constants for <code>number</code> that I can find are all too big, and there doesn't seem to be a max/min value</p>
