At 3 was about the time dd7 was interested in those things as well, she just decided it's was time for her to learn how to tell time, the days of the week, months of the year ect... She would use a wall calendar and flip the pages to each month over and over again. The funny thing was that since she was already reading so well at this point I stopped her one time to say it from memory, so she said January, February, March, then she paused for a moment and her 18 month old sister (now 5)finished it up with the rest of the months of the year,lol. It was at that moment I realized I had two very smart little girls smile
