Kind of, but not exactly. Those are the hours their businesses are open. However, this takes one variable out of the formula, which is calculating the time difference. Rather than having to know the time difference and business hours, you'd only have to know the business hours. Also, it would be even easier if you just shared your availability, which is what matters anyway, but you don't have to calculate the time difference. There's only one variable to communicate, which is the universal time they would be available. It's super simple.
