Nice. I did something in 2020 in a spreadsheet to calculate some sort of a Big Picture Timeline of the family with a our own definition of Success and Failures. For me, I found that it is easier to see Weekends in a Straight line rather than the starting date (I have school going kids).

I did it pretty manually because this is something I do once every year around the year-end.

Here is the Google Sheet Template. Change/Add/Edit the "YYYY" sheet to the year you want and fix the dates (should not take you more than 5-min). I have included the year a family member is born in the "Data" sheet to calculate the key events in life - Kids Graduation, and whatever else you want to in sync with you, your partner’s age, and any event you want to track.
