How to teach this
The word "name" is the lever: Monday is the name of a day, June is the name of a month, exactly as Maya is the name of a person. Kids who hear days and months as names capitalize them naturally. Calendar time is free practice; the calendar is a wall of capitals.
Watch for: Days and months are names of specific things, so they're capitalized; seasons are not (summer, fall). Titles attached to names get capitals too: Ms. Lee, Grandpa Tom.
Common questions about capitalizing names and dates
- Why do days and months get capital letters?
- Because they're names. Monday names one specific day the way Maya names one specific person. English capitalizes names of specific things, and days and months belong to that club. Framing it as the name club makes the rule feel logical instead of arbitrary.
- Does "birthday" get a capital?
- No; birthday is an ordinary word, not a name. My birthday is in June capitalizes only June. Kids often over-apply the new rule for a while, which is healthy; a quick "is it the name of a person, day, or month?" test settles each case.
