Well, honey, there are 24 hours in a day, so if you want to know how many hours are in three and a half days, you just gotta do some simple math. Three days would be 72 hours (3 days x 24 hours), and half a day is 12 hours (0.5 days x 24 hours), so in total, you've got yourself 84 hours (72 hours + 12 hours). Easy peasy, lemon squeezy!
There is 30 minutes in a half hour. There is no hours in half hours.
