| Parameter | Description |
|---|---|
| year | Required. A four digit number representing the year |
| month | Required. An integer between 0 and 11 representing the month |

Example 1
In this example we will get how many milliseconds there are from 1970/01/01 to 2005/07/08 according to universal time:<script type="text/javascript"> var d = Date.UTC(2005,7,8); document.write(d); </script> |
The output of the code above will be:
1123459200000 |
Example 2
Now we will convert the output from the example above into years:| <script type="text/javascript"> var minutes = 1000 * 60; var hours = minutes * 60; var days = hours * 24; var years = days * 365; var t = Date.UTC(2005,7,8); var y = t/years; document.write("It's been: " + y + " years from 1970/01/01"); document.write(" to 2005/07/08!"); </script> |
The output of the code above will be:
| It's been: 35.62465753424657 years from 1970/01/01 to 2005/07/08! |
