I am creating a datetime string that looks like this: 2010-07-15 11:54:21

And with the following code I get invalid date in Firefox but works just fine in Chrome

var todayDateTime = year + '-' + month + '-' + day + ' ' + hour + ':' + minute + ':' + seconds;

var date1 = new Date(todayDateTime);

In firefox date1 is giving me an invalid date, but in chrome its working just fine what would the main cause be?

You can't instantiate a date object any way you want. It has to be in a specific way. Here are some valid examples:

new Date() // current date and time

new Date(milliseconds) //milliseconds since 1970/01/01

new Date(dateString)

new Date(year, month, day, hours, minutes, seconds, milliseconds)

or

d1 = new Date(October 13, 1975 11:13:00)

d2 = new Date(79,5,24)

d3 = new Date(79,5,24,11,33,0)

Chrome must just be more flexible.

From apsillers comment:

the EMCAScript specification requires exactly one date format (i.e., YYYY-MM-DDTHH:mm:ss.sssZ) but custom date formats may be freely supported by an implementation: If the String does not conform to that [ECMAScript-defined] format the function may fall back to any implementation-specific heuristics or implementation-specific date formats. Chrome and FF simply have different implementation-specific date formats.
