GROUP TICKET QUESTION

I have a question for anyone in the know. I have tickets for this Friday the 13th through my work. they are part of a group ticket program. I wanted to know if these tickets can be used on any day or or just the day indicated by our company. the weather is possibly supposed to be crappy on Friday and it takes 2 hours to get there and I can only stay until 4 due to babysitter issues. Any help with this would be appreciated.

Thanks
