Using calendars to find days of the week, calculate days between dates, and work out what day a future or past date falls on.
Where your child meets this in real life: Planning events, working out birthdays, counting down to holidays
SEAGReady breaks calendar and date calculations into 3 steps, taught in order so each skill builds on the last.
Find specific dates on a calendar and identify the day of the week for given dates
Calculate how many days between two dates in the same month, or find a date X days before/after another date (no month boundary crossing)
Count days or determine day of week for dates in adjacent months, using knowledge of month lengths and the 7-day cycle
Three free sample questions from our calendar and date calculations course. Every question comes with a full explanation, and hints that guide without giving the answer away.
