- "What date was 18 years ago?" — pick today, subtract 18 years.

Business-day mode
When you choose business days, the calculator skips Saturdays and Sundays. Adding 10 business days from Monday lands on the second Friday after — useful for SLAs, financial settlement windows and shipping commitments.
