Practical Examples
Pregnancy: Jan 1, 2024 (last period) ~ Oct 7, 2024 (due date) = 9 months 6 days
Tenure: Mar 2, 2020 (hire) ~ Nov 16, 2024 = 4 years 8 months 14 days
100-day Anniversary: Aug 8, 2024 ~ Nov 16, 2024 = 3 months 8 days = 100 days

Weekday/Weekend Distinction
Automatically distinguishes weekdays (Mon-Fri) from weekends (Sat-Sun). Useful for calculating working days or project schedules. Note: Public holidays are not considered, so deduct them separately for accurate working days.
