1) I'd much rather have to deal with 24-hour settings than PM/AM.
I'd also like to have both a 24:00 and a 00:00 option:
"From 20:30 to the end of the day" would be 20:30 to 24:00
"From beginning of day to 14:00" would be 00:00 to 14:00
I believe this format is more intuitive for most people, especially if English isn't their first language.
2) There are cases where you need to set more than one ranges of hours per day. Example 1: When a period traverses midnight, like when we have weekly shifts from 17:00 to 05:00 next day. For Tuesday I'd have to set 2 ranges: 00:00 to 05:00 (for the shift that started on Monday and crossed into Tuesday) and 17:00 to 24:00 (for the shift that started on Tuesday). There is no way I can set this in Freshdesk in just one Business Hours rule as it stands now. I doubt that the solution would be to create two complementary Business Hours rules as that would create a mess with, for example, SLAs.
In my view, a control where you slide the mouse and can select one or more time ranges per day would be much preferable (this is the type of control that Zendesk uses in Settings > Schedule > Business hours ).
Alternatively, even allowing for just 2 time ranges per day, using conventional drop-down controls, should be enough for the majority of your customers.
