### Rules for Clocks and Calendar Questions and Answers

### Rules

- These questions are equally tricky as others in the aptitude section. There are some rules which can help you to do your best with these tricky questions. Check the below-given rules for better insights:
- Beginning from 1st AD, every 100th year is said as a non-leap year, however, every year in 4th century is a leap year. Thus, whichever year that can be divisible by 400 is said to be a leap year, such as 1200, 1600 and 2000. Moreover, the years 1800, 1900 cannot be non-leap years since they can be divisible by 100, and not 400.
- When each hour passes, both hands of the clock overlap on one occasion. Within the time of 12 hours, the hands overlap 11 times. It occurs as a result of just one such occasion coming between 12 and 1’o clock.
- Within one hour, two right angles are started to shape and almost within 12 hours there is said to be 22 right angles shaped by the hands of the clock. It occurs by reason of right angles outlined by the hands of the clock that are minute and hour hand at 3’o clock as well as 9’o clock.
- The hands stay in the similar straight line when they overlap or are opposite to facing each other.
- The hands of the clock are 15-minute spaces apart when the hands are at right angle.
- A normal year has 365 days, which implies 52 * 7 + 1, or 52 weeks plus one day. The extra day, is known as an odd day.
