getDay() return different value to different browsers/computers

Question

I have this code to find the value of weekday of 2012-01-24 (which should be Tuesday):

============

var myDay=new Date();

myDay.setUTCFullYear(2012, 0, 24);

document.write(myDay.getDay());

============

However, different browser/computer shows me different value, some gives 1, some gives 2.

Any clue to fix this problem?

Thank you in advance!

Answer 1

For myDay = new Date(); , use myDay.getUTCDay to get one value for each browser and country. The ordinary getDay method returns a locale-specific value.
