I am looking for a clock chip similar to an alarm clock chip with several events you can select.

Thanks. I looked through these and the closest I can seem to get is a "dual" alarm chip. I was really hoping I could find something off the shelf with 3 or 4 events and separate alarm output pins for each. I am trying to avoid cobbling up a processor and RTC for this if it already exists.

There used to be some really neat VLSI's for clock circuits, but these days a PIC or similar processor is simple, dirt cheap and scarcely cobbled together.
Cheers.

Hello Ken,
Or use a MSP430 plus a watch crystal. It can run on a few uA, keep time and handle all kinds of events.
Regards, Joerg
