In the Table View of the Life Calendar, edit the formula of the Start Date column. It may look slightly intimidating if you are not familiar with formulas, but you only need to edit TWO numbers.
Below is the formula as it appears in the column:
dateSubtract(dateAdd(dateAdd(dateAdd(fromTimestamp(0), ((31)), "days"), ((10)) - 1, "months"), toNumber(prop("Year")) - 1970, "years"), 16, "hours")
((31)) to be the date of your birth. Mine is the 31st, for example.((10)) to be the number of the month of your birth. Mine is October, the 10th month, for example.This task is a little more involved due to some Notion restrictions, but it is also a one-time, simple task. Add or modify the Year column for each year to include every year of your hypothetical life. For example, I was born in 2000, so I added the years 2000 through 2080. If you were born in 1986, you might add the years 1986 through 2066, or 2086 if you're feeling lucky.
This is the part where Notion does everything for you. You'll see every week you live filled in with an Earth, and every moon you live filled in with a Moon. Each year you live will be marked off with a Sun.
This is a perspective and big-picture journaling tool, not an existentialism tool.
This is a place for you to go and appreciate the time you've lived and the things you've done.
This is a place for you to come and see how your future might pan out, and to help yourself make the best of the moments you live.
