A friend gave us this really amazing calendar (she found it at a garage sale, but it would probably be pretty easy to make one like it). It’s made with velcro so it’s easy for the kids to use. As you see, it has the day, date, month, year, weather, and season.
It has become our first-thing-in-the-morning ritual, and really helping my 6-year-old to understand how days, months, years, and seasons work. Plus, it’s fun.
