Details about the calculations and spreadsheets that can be used to calculate solar data are available on the
solar calculation details
page.
Having Trouble?
Check your Time Zone -- Is the time zone set correctly for this
location? Our calculator attempts to determine the correct time zone for
the given location and date, but because time zones and the start and
end dates of Daylight Saving Time sometimes change, this value may not
be accurate for historical or future dates.
Click the Show Sunrise, Show Sunset and Show Azimuth checkboxes to
display color-coded lines on the map indicating the direction of
sunrise, sunset and solar position based on the Local Time and Date entered.
This solar calculator is provided for research and entertainment
purposes only. Due to variable atmospheric conditions and uncertainty
inherent in the algorithms used, the actual observed values of sunrise,
sunset and solar position may differ from the results presented here.
