Another simple Desktop Widget using PySimpleGUI
The "Days Since _______" Widget
This widget counts the number of days since some date of your choosing.
Maybe you want to track the number of days since the start of the year.
Or perhaps when you got married.... or divorced.... or stopped some activity
Or started some activity.... you get the idea. It tracks a time delta in days
