Yes, because working hours nowadays are simply flexible.
You don't go to the office every day at 9 a.m. and leave at 6 p.m.
Instead, over time habits creep in that usually depend on the day of the week. Therefore, you can define different working times for each weekday. You can also specify if you work in home office on certain days and therefore will only be available for virtual meetings.
Of course, you can also specify if you have a complete day off.
