Skill: Use a calendar to identify dates

Explanation and Free Practice Resources

A calendar represents time in an organized sequence of days, weeks, and months; a date is identified by its month and day number, and its position can be used to determine the corresponding day of the week. The learner interprets the order of dates, including that consecutive dates advance by one day and that months have different lengths, without extending to elapsed-time calculations, leap years, or more complex date systems.

Detailed Explanation: Use a calendar to identify dates

A calendar puts the days in order. The names at the top tell the days of the week. Each number is a day in the month.

Here is part of a calendar for March:

SundayMondayTuesdayWednesdayThursdayFridaySaturday
1
2345678
9101112131415
16171819202122

Example: What day of the week is March 12?

  1. Find the month: March.
  2. Find the number 12.
  3. Look straight up from 12 to the name of its column.
  4. The number 12 is under Wednesday.

So, March 12 is a Wednesday.

Remember, the next date is one day later: March 13 comes after March 12. Dates continue in order across each row and then move to the next row.
