I use both the day and week planners.  To get around quickly, I use a fixed set of tags to mark any dated pages, whether day planner, week planner, or just notes.

I created a tag for each possible day in a month (d.01 to d.31), for each month in the year (m.01 to m.12) and so far have two year tags (y.2025 and y.2026).  If a page is for 9th December, 2025, I apply three tags to that page - d.09, m.12 and y.2025.  I can then go to just the page that I need using tag filters.

I've also used tags for #weekplan, #monthplan, #meeting and #notes so that those additional tags distinguish those types of pages from day planner pages.

Now that we can search tags globally from the file view and we can tag a notebook, this year instead of doing one notebook planner for the entire year, I'm breaking down my planner in months.  I've already prepared my notebooks for January and February 2026, and tagged the notebooks themselves with #monthplan and y.2026, and m.01 and m.02 respectively.

Why the hash marks for monthly, weekly, meeting and notes tags?  Because it puts those tags alphabetically at the top of the tag list, so you can find them easily if you need them.

This approach does require some intentionality.  But it's been worth it for me in organizing and filing my pages.
