Thanks for this @rubaboo!
I used your gsheet template to help me shortcut the creation of my usual 2021 planner, and I updated my original post with a link to a copy-able 2021 dynalist planner over here: **UPDATED FOR 2021** Here's my Yearly Planner Template
(I made one small change to your template because in the dates I prefer to put a dash in between the month and the day e.g. mm-dd instead of mmdd)
