This clock shows you the hour, minute, second, day of the week, month, date, and the year! No negative comments, this was very time-consuming. HOW TO GET TO A 12 HOUR CLOCK: Click the 24 hour icon to go to 12 hour. It switches to a 12 hour clock instead of a 24 hour clock. A cyan circle appears when you click the 24 hour icon. Note that the 24 hour icon switches to 12 hour icon when you click it. Anyway, when you click the cyan circle, the 12 hour icon goes back to being 24 hour icon and sets the clock back to 24 hours. Hope you get it. If you don't, sorry, you won't be able to turn 12 hour clock on.
