Your saved days

Day Book keeps one hand-picked observance for all 366 days (Leap Day counted on leap years), drawn from the two calendars that track them: National Day Calendar and National Today. Both list more days per square than fit on a page — the two links above go straight to their entries for whatever date you’re looking at. Arrow keys move a day, T returns to today, R lands somewhere at random.
