Back in 2023, I created a simple version of this concept for my own life events (https://days.rory.codes) and shared it on HackerNews[1] where it received a fair amount of commentary.
A handful[2] of people asked if they could duplicate the project for themselves - so I built this expanded version that lets you sign in, add your life events, and see your own timeline visualised day by day. Data is encrypted at rest and everything is private, though you can make your timeline public and shareable if you wish.
Let me know what you think!
