Why business days matter for sprints
Using workdays prevents overpromising when weekends or holidays reduce available time. Teams can compare sprints fairly across months with different holiday loads.

Start Mon, Sat–Sun weekend, exclude start, include end.
Ends second Friday.
15 business days
Same start, same mode.
Ends third Friday.
