Convert the 1st month to a digit such as Feb = 2 Convert the 2nd month to a digit such as Mar = 3 Create a date variable for the 1st month as: var d1 = new Date(year, MM1, day, hours, minutes, seconds, milliseconds); Create a date variable for the 2nd month as: var d2 = new Date(year, MM2, day, hours, minutes, seconds, milliseconds); Use zero or null for the non-used fields. Use one of the date functions to convert the date (probably to its UTC value) do the math and then convert back.
