@ everyone in this thread:
Currently there’s no way to make Monday the first day of the calendar in the stock calendar, and as far as I know it’s not on the radar just yet. However, there are ways to “hack together” a custom calendar view either based on a grouped table or on custom HTML.
Here’s just the doc where I did it:
Interactive (table with groups):
HTML rendered (compact for printing):
I’m consulting on Coda and making docs for hire, so if you’re interested in having this integrated into your setup, DM me or write at paul@codatricks.com
