I am sure many Powerusers know the struggle of maintaining a calendar of some sort in Dynalist.
I got across this Blogpost which offers one calendar that works forever.
Just copy the list with the day the month starts and viola: No more typing every month.
Because I did not like the initial date and weekday formatting I decided to hack together a little python script and create something similar for Dynalist.
Let me know if you are interested in different formatting etc.
