Should I use dates as chapter titles?

I’m writing an autobiography based on coincidence and synchronicity through numbers. Each chapter tells a story of events that happened on specific dates. The specific dates are crucial to the story.


1. Do I use the specific date as a chapter title?
or

2. Do I give my chapters a descriptive title instead of a date?
or

3. Can I do both, and if so, which one’s above the other?

Thanks

Thankyou Nick, gentleman of a refined age!
