Terri, I just use the Calendar app included as a default in Windows 8. I set up an appointment or a reminder and it tells me ahead of time what's coming up. You can set it to simply remind you with a notice in the upper right corner of your screen or you can have it send you can email.
EDIT: I just found a free app in the App Store called RemindMe... sounds like it might be what you're looking for. Just bring up the Charms on the right and select Search; type in reminders and click on Store in the list below and it will bring up all the apps that are reminders.
Fireplace, yarn, knitting needles, books, wine... check. Yup, I'm ready for winter.
