We are learning how to read the 24 hour clock

Midnight – Midday There are 24 hours in a day! The first 12 hours of the day are from: Midnight – Midday

In 12 hour time We count from midnight to midday Then we count from midday to midnight!

Count the hours in the day…

In 24 hour time we count from... 1 to 24! 1,2,3,4,5,6,7,8,9,10,11,12, 13,14,15,16,17,18,19,20,21,22,23,24!
