Calculation of "Day of The Week" i.e. Calendar is an extremely small topic in the general mathematics but this topic is very important from the point of view of examinations also from the point of view of general awareness. The facts and basics of Calendar are such that they make it a very interesting topic to read and to understand. I have noticed that the students have many doubts about the calculation of "Odd Days" and the figuring out the Leap years. Actually, the topic of calendar mainly revolves around the above-mentioned two concepts i.e. "Odd Days" and Leap Years. I have chalked out the course content of this course accordingly keeping in view the things discussed above.

Starting from the basics and fundamentals of solving calendar problems, this course deals with advanced and difficult questions which are generally asked in different exams. This course is equally useful for both school students and the students who are preparing for competitive exams and Math olympiads. I have made all-out efforts to make things as simple and easy as possible. After going through the content of this course, all possible problems related to calendars can be solved with ease and without doing many calculations. The course becomes extremely handy for the students who are doing preparations for their competitive exams or they are trying for Math olympiads. After learning various facts and nuances about the calendar theory most of the questions can be answered in a matter of seconds. This course is equally useful for parents and grand parents who want to teach their children so that children could grasp the concepts with full clarity and understanding.

Out of the total time of one hour's course material, I have taken about thirty percent of the course time in explaining the theory part of calendar to enable the students to understand the facts and basics of the topic thoroughly thereby grasping the concept with total clarity.

In order to include all possible types of questions that are frequently posed to the students in different exams, I have made an extensive search on the internet and have visited various websites that deal with math fundamentals and helping the students in solving quantitative aptitude.
