Hello guys, well my problem is that I changed the datetime fields in holidays with date fields and I added a float field for the hours (with web timepicker widget), my problem is that this field has a limit, between 9:00 - 17:30 are the hours that you can choose, but in summer, the fridays should be 9:00-14:00 and I haven't idea how I could do it.

Could tell me some advices? Thanks!! (and sorry for my english)
