Years and months are applied first, then weeks and days, so the order is not interchangeable: three months plus 30 days can differ from 30 days plus three months.
What 15 days actually contains
A count of calendar days is not a count of working days, and for anything with a deadline the difference is the part that matters. Between Sep 29, 2026 and Oct 14, 2026 there are 11 weekdays and 4 weekend days.

The holidays inside this span
One federal holiday falls between the two dates. Federal holidays close government offices and most banks, which is what turns a 15-day deadline into a shorter one in practice.
