The start time for the event is 7:15 is that 7:15 SHARP? Or if I come a half hour later will it be OK?

Yes! That means sharp! We understand that in some cultures the start time is not the actual estimated time of arrival for the guests. The JICNY is a very diverse international community and all the members work on different cultural standards of time. In our efforts to keep everything fair to everyone, we ask that you show up on time to our events.
