Time

1. Analogue clocks are those with an hour hand and a minute hand. They only show twelve hours so the time on analogue clocks is always m. or p.m. depending on whether it is morning or evening.

2. Digital clocks can show either twelve hours or twenty four hours – in twelve hour, it will be m. or p.m. but not in twenty four hour time.

Example 1:

All three of these clocks are showing the same time. We would read this as ‘ten to three’ or 2:50.

It’s important to know the conversions for time as many questions may have different units. You must first convert all the different lengths of time into one unit then do the problem.
