The arrow and the N symbol on the card should be aligned to point northwards. The use of a compass or map is advisable to help find north.
Once pointing North hold the card flat and the sunset will be indicated by the lines on the left hand side (i.e. the west) and the sunrise on the right hand side (the east). Each line shows the direction that the sun will rise or set for the month associated with it.
The card is transparent so it can be layed on top of a map. Simply align the card with north on the map and place the centre of the card over your chosen location. It's then easy to trace where the surise and sunsets will be.
