NOTES:
The times in the table are based on averages and may be in error by 10-15 seconds in January and December.
If your area has Daylight Saving Time in the summer, we recommend that you highlight or draw a box round the relevant time, and write "Add one hour for Daylight Saving Time" at the foot of the relevant months. Note: In the United States of America (USA), Daylight Saving Time is in effect from the first Sunday in April through the last Sunday in October.
Before printing, set page to landscape mode (File; Page Setup); you may need to make the margins narrower.
