Calendar & Dates Questions with Solutions

Calendar questions ask you to find the day of the week for a given date, or how dates and days shift between years. The core idea is odd days: the number of days left over after complete weeks. An ordinary year has 1 odd day and a leap year has 2. A century year is a leap year only if it is divisible by 400, so 2000 was a leap year but 1900 was not. Exam questions test finding the day for a given date, finding when a calendar will repeat, and working forward or backward from a known day. Month codes make the day-for-date method quick once memorised. Remember that the day on 1 January moves forward by one day after an ordinary year and by two days after a leap year. Practise the calendar questions below, each with a step-by-step solution using the odd days method.
