Given a starting Date, return the next business day (Monday through Friday). Move forward one day at a time and skip Saturdays and Sundays. Return null when the input date is null.

Examples:

Date next = nextBusinessDay(Date.newInstance(2025, 10, 1));
// Results: 2025-10-02

Date afterFriday = nextBusinessDay(Date.newInstance(2025, 10, 3));
// Results: 2025-10-06

Hints:

  • Check for a null start date before processing
  • Use a loop that advances one day until it lands on a weekday
  • Convert the Date to a DateTime to determine the day of week
  • Sunday and Saturday should both roll forward to Monday
