Although I’ve also been using just the search pane to be honest.
Formatting things as 2020-11-11 when applicable. Searching 2020-11 to find all dates.
So far have mostly been creating dates for future events.
My notes for the day, month, and year have #day, #month, #year in them so I can find them. At least that’s how I’ve been using #day haha.
Haven’t been using Obsidian for long yet.
