Print Your Solar Noon Calendar
for your exact longitude wherever you are in the world

The time of solar noon depends on the Equation of Time and on the difference in longitude between your location and the standard meridian of the time zone you are in. It is slightly different for every day of the year. Our unique Solar Noon Calculator will provide you with a table showing the exact time of solar noon for your location for each day of the year.

If you prefer, you can print out the values of the Standard Time Correction, which gives you the amount to add to, or subtract from, the time on your sundial to obtain the time shown by your watch. The Standard Time correction is the sum of the Equation of Time, and the longitude correction; the longitude correction is the time the sun takes to travel between your longitude and the longitude of your standard meridian

You can find the input data you need for our unique Solar Noon Calculator from or many other websites.

Note that our calculator requires that your latitude and longitude be in decimal format. If your co-ordinates are in Degrees, Minutes, Seconds please click here.

  Standard Time Correction
Solar Noon displays the exact time of solar noon each day.
Standard Time Correction is the amount you have to add to, or to subtract from, solar time on your sundial to get the time shown on your watch (see note above)

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: The values given by the Calculator are averages for the full leap year cycle of four years (1,461 days) and change slightly from year to year. The range of variation for the 1st day of each month is shown below:

Jan - 21 secs May - 5 secs Sept - 6 secs
Feb - 6 secs June - 7 secs Oct - 15 secs
