Operators available for the years

The following arithmetic operators can be used with the Property Year:
  • ++ and --
  • += and -=
StartDate is Date = "20011212"
HEX@ Start.Year++ // Add 1 year to HEX@
HEX@ Start.Year+=5 // Add 5 years to HEX@
HEX@ Beginning.Year-=5 // Take 5 years from HEX@

Leap years

If the date handles corresponds to February 29 of a leap year, adding or subtracting a year to the date also changes the day. For example:
StartDate is Date = "19960229"
// Add 1 year to the date
StartDate.Year++ Date
// StartDate is "19970228"
