Sunrise Sunset Calculator
This is my shareware program that calculates sunrise, sunset and twilight times for locations worldwide.
Once you set your location, you can hover your mouse over the sun icon to
get some basic sunrise and sunset information or you can click on the icon to get more
detailed information.
The program uses formulas which are accurate year-round to within a
few minutes for all states except Alaska. Even in Alaska it is generally accurate to
within five minutes.
Twilight Too
In addition to calculating sunrise and sunset times, the program calculates three different twilight times: civil, nautical and astronomical.
Also calculated is how much daylight and total usable light there will be for the current day.
City List
When the program is started the following window will come up for a few seconds;
to get it back simply right-click on the sun icon in the taskbar by the clock.
You can then choose a city that the program will use to calculate all sunrise and sunset information.
The Sunrise Sunset Calculator comes with 76 U.S. cities, 14 Canadian cities and 40 international cities.
Add Your Own Location
If your city is not listed in the city list, you can add your own custom location. The freeware version
is limited to one custom location.
Future or Past Sunrise & Sunset Times
Do you need to know the times of sunrise or sunset for a certain location for a particular date? Try using the
custom calendar option available at www.sunrisesunset.com. It will
display a one month calendar for a location selected from a pre-defined list or from a user-entered form.
Update for Version 1.0.1
When requesting Daylight Saving Time (DST) information from Windows 95/NT, the operating system was always returning DST based on the North America settings, i.e. first last Sunday in April to last Sunday in October.
The program has been corrected to get the correct DST from the Windows operating system.
Update for Version 1.0.2
New sun icons and the more information screen shows sun times for tomorrow.
