Questions asked from this topic is based on watch and calendar. Questions asked on watch in examination focus the angles of hands of watch and questions asked on calendar in examination refers to the date and day on a prescribed given time period. To solve these questions, a candidate must, know the term of watch and calendar.

Though we all know how to read time on
a clock, yet solution of questions on clock requires some level of intelligence which is above on common level. We have laid down properties of clock with illustrative examples so that students may not find any dificulty Minute Hand while solving questions given in the exercise. The dial of the clock is numbered from Minute Hand 1 to 12 in such a way that each subsequent number is equidistant (5 min spaces apart) from the preceeding number.It has two needles known as minute hand and hour hand. The distance between two consecutive numbers is 5 min. It means that the circumference of the clock measures 60 min spaces. When hour hand travels 5 min spaces, the minute hand travels 60 min spaces. In this way, by travelling 60 min spaces, the minute hand gains 55 min on the hour hand.
Calendar
Calendar measures a day, a week, a month and a year. In other words, we can say that calendar is the measurement of a year.
Ouestions based on calendar are of set pattern and hence follow set rules. We are giving below the definition/meaning of certain words which are used in solving questions on calendar.
Odd Days We know that a week contains 7 days counting from Monday to Sunday. So, any number of days, which are more than complete number of a week in a given period are called odd days. e.g., a period of 10 days contains 3 odd days, 11 days contains 4 odd days, 12 days contains 5 odd days. But period of 14 day's contains zero odd day.
Therefore, in finding number of odd days in a given period of time, one has to divide that period by 7. If it is completely divisible by 7, it contains zero odd day and if it is not divisible by 7, then remaining number of days are the odd days.
Leap Year The year which is divisible by 4 is called Leap Year. But every century which is Divisible by 4 is not year. Every 4th century is a leap year. e.g. 400, 800, 1600, .. are all leap years but centuries like 100.1 600, are not leap years. An ordinary year has 365 days ie., (52 weeks + 1) day a leap year has 366 days ie.. (52 weeks + 2 days)
