How to interpret timetables
Timetables are lists of times that present information about when something will happen.
They can also tell you how long something will take. This is also known as its duration.
When you read timetables, you often need to read across the rows and down the columns of the table.

On this bus timetable, each row shows the arrival times of a bus at different stops.
So reading across a row tells you the different times when a bus reaches that stop throughout the day.

Finding a specific time on a timetable
Most timetables for travel, for example those for buses, trains, trams and aeroplanes, use the 24-hour clock. This is to reduce the risk that someone may read the time incorrectly on the timetable.
You can use a timetable to find a specific train to travel on and find out what time it will arrive at a destination.
This part of a train timetable shows trains travelling from Newcastle to Edinburgh.

To find a time that a train leaves Newcastle, first find the column labelled ‘Leaves Newcastle’, then read down the column to find the train times.
Look at the row for the train leaving Newcastle at 13:52. To find out what time it arrives in Edinburgh, read across the row to the arrival times. It arrives at 15:16.
Calculating durations using a timetable
On this part of a bus timetable, the buses leave Thornton Interchange every 15 minutes. However, some of the buses take longer than others to get back to Thornton Interchange.

Two of the buses on the timetable do not stop at every stop, so they have a shorter journey time.
You can calculate the duration of the 06:30 bus journey, from Thornton Interchange back to Thornton Interchange, by working out the difference in time between the departure time and the arrival time.
You can see the bus departs at 06:30 and arrives at 07:28.
You might use a number line to find the difference between these times or you might count on in your head.

06:30 to 07:00 is 30 minutes.
07:00 to 07:28 is 28 minutes.
30 minutes + 28 minutes = 58 minutes
Comparing durations from a timetable
You can compare durations from a timetable by first calculating the durations then comparing their length in time.

Chloe takes the 06:25 bus from Main Road to Saltwell Common. Then she takes the 07:40 bus from Saltwell Common to Thornton Exchange.
The first journey is 30 minutes as the bus leaves at 06:25 and arrives at 06:55.
The second journey is 25 minutes as the bus leaves at 07:40 and arrives at 08:05.
The second part of her journey is shorter in time than the first part of her journey.
Example 1
The earliest train on the timetable leaves Newcastle at 12:39 (24-hour clock), which is 39 minutes past 12 noon (12-hour clock).
If it arrives on time, it will arrive in Edinburgh at 14:13 (24-hour clock), which is 13 minutes past 2 in the afternoon (12-hour clock).

You can use a number line to help calculate the difference in time from a trains departure (leaving Newcastle) to its arrival (in Edinburgh).
How long is the journey from Newcastle to Edinburgh on the train that leaves Newcastle at 12:39?
✓ The total journey time is 1 hour and 34 minutes.
The train leaves at 12:39, which is 21 minutes before 1pm.
The time from 13:00 (1pm) to 14:13 (13 minutes past 2) is 1 hour and 13 minutes.
Adding this together:
21 minutes + 1 hour and 13 minutes = 1 hour and 34 minutes

Example 2
Take a look at the five sets of bus times shown on this timetable.

Sally is travelling to Legrams Lane from Main Road, and she needs to arrive by 07:20.
What is the latest bus she can take?
✓ The latest bus Sally can take from Main Road to arrive at Legrams Lane by 07:20 is the 06:15 bus.
There are only two buses Sally can take from Main Road to arrive at Legrams Lane by 07:20:
- the 06:00 bus
- the 06:15 bus
The 06:30 bus does not stop at Legrams Lane so the latest bus she can take is the 06:15 bus.

Example 3
Here’s a different type of timetable.
Rohan made this timetable because he wanted to make sure he had time at the weekend to finish his homework and also time to relax and do the things he enjoys, such as playing with his friend Patrick or watching TV.

How much time each day did Rohan spend on homework?
✓ Rohan spent 2 hours 30 minutes on homework each day.
In Rohan’s timetable, there are two blocks of time set aside for homework. Each block is 1 hour 15 minutes long.
1 hour 15 minutes × 2 = 2 hours 30 minutes
