Leap years occur every 4 years, adding an extra day (Feb 29). Years divisible by 100 are not leap years unless also divisible by 400.

Business days typically exclude weekends (Saturday & Sunday). Some calculations may also exclude public holidays.

Months have 28-31 days. Feb has 28 (or 29 in leap years). Apr, Jun, Sep, Nov have 30. Others have 31.
