This Script finds the difference between 2 dates. The result is Days Count.
Date Object.
Initializing Dates
new Date() // current date and time
new Date(milliseconds) //milliseconds since 1970/01/01
new Date(dateString) // mm/dd/yyyy format
new Date(year, month, day, hours, minutes, seconds, milliseconds)
new Date(milliseconds) //milliseconds since 1970/01/01
new Date(dateString) // mm/dd/yyyy format
new Date(year, month, day, hours, minutes, seconds, milliseconds)
example
Difference between 04/04/2014 and 04/08/2014 is 1.
