Skill: Read calendars

Explanation and Free Practice Resources

A calendar represents time in a repeating structure of days, weeks, and months, enabling interpretation of dates by matching the day of the week, date number, and month, and identifying the order and length of months. Learners determine intervals in days or weeks by counting calendar units and distinguish a date (when an event occurs) from a duration (how long it lasts), without requiring leap-year rules or more advanced calendar systems.

Detailed Explanation: Read calendars

A calendar organizes days into rows of weeks. Each column shows the same day of the week.

Use this calendar:

SundayMondayTuesdayWednesdayThursdayFridaySaturday
1234567
891011121314
15161718192021
22232425262728
2930

Example: A library visit is on June 10. A class trip is on June 13. What day of the week is the trip, and how many days after the library visit is it?

  1. Find the number (10)(10). It is in the Tuesday column, so June 10 is a Tuesday.
  2. Find the number (13)(13). It is in the Friday column, so June 13 is a Friday.
  3. Count forward from June 10 to June 13:
    • June 10 to June 11: 11 day
    • June 11 to June 12: 22 days
    • June 12 to June 13: 33 days

So, the class trip is on Friday, June 13, and it is 3 days after the library visit.

Remember: June 13 is a date, or when something happens. 3 days is a duration, or how long the wait lasts.
