And boooom!! Cinderella comes back to her actual self right in front of the prince just because the man did not know to read time..

"Oh no.. Its past 12! I was supposed to leave earlier" :'(

"Sir! Something has happened to Cinderella!!!"

"Cinderella? Is that you?"

And thus, Cinderella's story did not end the way we always heard it does.

JANTAR MANTAR, JAIPUR

AMAZING FACT!!

The Jantar Mantar, Jaipur is a collection of 19 astronomical instruments built by the Rajput king Sawai Jai Singh II, the founder of Jaipur, Rajasthan. The monument was completed in 1734. It features the world's largest stone sundial, and is a UNESCO World Heritage site.

(Sundial- A type of clock used in past times that uses the dark shape (shadow) caused by a pointed piece of metal being between the sun and the clock surface to show what the time is.)

You have already studied how to read time in grade IV.

Let us revise that.

"Mother, in this clock I can see that the hour hand is on 10 and the minute hand is on 2 which means 10 minutes i.e. that the time is 10:10. But mother, what is the third and the red arm for?"

"This hand is called the seconds hand. The second is a very small unit used to measure time less than a minute. The face of a clock is a circle divided into 60 equal parts. When the second hand moves one part, it takes one second. When it completes one round of the clock face, it moves across all 60 parts. This takes 60 seconds. In the same time, the minute hand moves one place, which means that one minute is over. It means that, 1 minute is equal to 60 seconds.

So here, the seconds hand is indicating 26 seconds."

“Father, You must have worked very hard in the fields today. How long were you working ?”

“I was in the field from six o’clock to seven o’clock."

“You’re this tired even though you were in the field for only one hour ?”

“No, no, I was in the field from 6 in the morning till 7 in the evening!

To avoid such mistakes, it has been internationally agreed that as the clock strikes 12 midnight, one day ends and the next day begins. From that moment on, the clock shows the time for the next day. When one hour passes after 12 midnight, it is 1’o’clock. After that, it is 2, 3, 4, …, 12 o’clock in serial order. After 12 noon, again it is 1, 2, 3, …, 12 o’clock in serial order. The time before 12 noon is stated as ante meridiem or am. The time after 12 noon is stated as post meridiem or pm. This method of measuring time is called the 12 hour clock.

The 24 hour clock 

The 24 hour clock is used to avoid this division of the day into ante meridiem and post meridiem. This method is used in timetables for trains, planes, buses and long-distance boat journeys. In this method, instead of starting again from 1, 2, 3 after 12 noon, we continue with 13, 14, 15,…,24. In a 24 hour digital watch, time is shown only in the form of numbers. It does not have hands. In such a clock, 20 minutes past 6 in the morning is shown as ‘6:20’ and 20 minutes past 6 in the evening is shown as ‘18:20’. 23:59 means 59 minutes after 23 and one minute later, 24 hours will be complete. The digital clock will show this time as 00:00 at midnight and the day will change. At that time, a 12 hour clock shows 12 midnight.
