A calendar helps us name today, remember yesterday, and plan for tomorrow. The days of the week repeat in the same order every 7 days, which makes a weekly pattern. The months of the year repeat in the same order every 12 months, which makes a yearly pattern.
Learning these names helps children talk about school, birthdays, holidays, and seasons.

Common Mistakes to Avoid
- Skipping days in the weekly order is wrong because the days always follow the same pattern from Sunday to Saturday.
- Thinking every month has the same number of days is wrong because some months have 30 days, some have 31 days, and February usually has 28 days.
- Saying a new year starts after any month is wrong because the year starts again after December and then January comes next.
- Mixing up yesterday, today, and tomorrow is wrong because yesterday is the day before today and tomorrow is the day after today.
