Logical Reasoning series: Solving questions on Calendars

Candidates appearing for competitive exams like CAT, UPSC, GRE, GMAT, TOEFL, SBI PO and many other exams often find questions on Calendars. It is important to have basic knowledge regarding the days of the week, months and year to solve the questions. A normal year would have 12 months and 365 days. Hence a normal year would have 52 weeks and 1 odd day. That means a leap year which comes in every 4 years would have 52 weeks and 2 odd days.
