Pick a difficulty level, look at the clock, and choose what time it is right now. The short hand points to the "hour," and the long hand points to the "minute."
Clocks having 12 numbers is a very old tradition β it's believed to come from the ancient Egyptians, who divided the hours of daylight into 12 parts to measure time.
The short hand (hour hand) goes all the way around the clock just once every 12 hours. So when it sits between two numbers (say, between 3 and 4), it still means "it's still the 3 o'clock hour" β the hour hand stays on the earlier number's hour until it fully reaches the next number. The long hand (minute hand) goes all the way around once every 60 minutes, adding 5 minutes each time it passes a number (12β0 minutes, 1β5 minutes, 2β10 minutesβ¦ 6β30 minutes). It's also important that the two hands move together: when the minute hand has gone halfway around (30 minutes), the hour hand has also moved halfway toward the next number.
Unlike a digital clock where you just read numbers, an analog clock asks you to look at both hands' positions at once, which can feel confusing at first. As you try higher difficulty levels and watch how the short and long hands move together, it will start to feel natural.
