Google calendar is a free tool for scheduling events and works much like all the other Google services. We've added a sample template in our Template Gallery containing the sample script used to pull data from your very own calendar. The cool part of all this is that any updates to your Google calendar will immediately be reflected in your signage. The sample we've provided is a mock-up of a hotel meeting room which displays any current or upcoming events scheduled for the room. As always you can rearrange or design the template any way you like and the functionality will not be affected.
