OK let's have a lesson for those who find this difficult. First, remember that little kids pick this up quickly and easily, so you can too!
We all know there are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day, right? and that the day is divided into the a.m. of 12 hours and the p.m. of 12 hours.
So analog clocks show those 12 hours as the numbers 1-12 evenly spaced around the clock face. Now look a little closer and you see it's also divided into 60 marks with a tick mark for each of the 60 seconds/minute or 60 minutes/hour. Hang on, we're almost there!
The little hand points to the HOUR number (1-12). If it's in between two numbers, that means the time is in between those two hours.
The big hand points to the MINUTE tick mark. Notice that the 1-12 numbers coincide with each 5th tick mark so it's easy to count them. Just count by 5's! So if the big hand is between the 3 and the 4, that means the minute of the hour is between 15 and 20, look at which tick mark for the exact minute.
Now, can you figure out how the second hand works? Good! Kindergarten dismissed!
I can tell the time perfectly well unless someone asks me what time it is. Then my brain is completely useless and I just have to twist my wrist around awkwardly to show them.
