I get paid on the same day each month, 23rd, and that’s the point I want to be able to budget. I’m finding the cross over of the month is confusing, is there a way to make YNAB treat the 23rd of the month as a new month?
Instead of working from May 23-June 22, June 23-July 22, etc. I'd recommend that you try to make your money last slightly longer. If you plan for your money to take you from May 23-June 26 (4 extra days) and June 27-July 31, then in short order you will be able to switch to planning (budgeting) in a single month's area starting in August.
There's no need to plan further ahead -- and indeed I find it counterproductive to do so -- so you can then switch to growing an Income Replacement category or other emergency-like funds.
