Do you want to know what the next working day is for a given date ? You will need the calendar to check this against. Use function module BKK_GET_NEXT_WORKDAY. The factory calendar you would need for this is Plant master data information, pick it up from T001W-FABKL.

Did you know date fields can be added to each other ? A week from now is sy-datum + 7 and there is a function module to check whether the date entered is plausible. Times too ? Times too.

This is a bit of coding that can be used to check for leap years: 

The CL_RECA_DATE class is available for quite a suite of date related operations. It can be used to calculate with dates, convert them to an internal format as a string, check the validity of a date, the list is not endless but over 30 methods are available to you.
