See TimeList()

Example:

See "Day Name : " + TimeList()[2]       # Sunday

Example:

See "Month Name : " + TimeList()[4]     # May

AddDays() Function

Syntax:

AddDays(cDate,nDays) ---> Date from cDate and after nDays

Example:

cDate = date()
see cDate + nl                  # 24/05/2015
cDate = adddays(cDate,10)
see cDate + nl                  # 03/06/2015

DiffDays() Function

Syntax:

DiffDays(cDate1,cDate2) ---> number of days (Date1 - Date2)

Example:

cDate1 = date()
see cDate1 + nl                                         # 24/05/2015
cDate2 = adddays(cDate1,10)
see cDate2 + nl                                         # 03/06/2015
see "DiffDays = " + diffdays(cDate1,cDate2) + nl        # -10
see "DiffDays = " + diffdays(cDate2,cDate1) + nl        # 10
