Question

Next, you will take the sunset times for at least one day in every month, and convert those times (measured in hours and minutes (sexagesimal-base)) to a decimal time (in hours). You will also need to convert the dates into a decimal format. I would suggest using a “Day of Year” calendar. Finally, you will find a model to predict sunset times using the “Curve Fitting” method outlined on Pages 588-91 in the textbook. You will need to find a computer model for you data set as well. You should keep at least 6 decimalplaces for the numbers you find.

Explanation / Answer

Ans-

You can enter a different time zone for a location by selecting "Enter Lat/Long -->" in the City pulldown box. Otherwise, the time zone associated with the selected city's Local Standard Time will be automatically entered. Selecting "Yes" in the Daylight Saving field will cause the resulting sunrise, sunset and solar noon times to be adjusted forward one hour. If you are uncertain of the time zone for a location, refer to our Time Zone Table.

The program retrieves the current date from your computer, and fills the month, day and year fields. To perform calculations for a different date, simply select a month in the pull down menu, and enter the day and four digit year in the appropriate input boxes. When entering a day or year, you will need to click the "Calculate Sunrise/Sunset" button to update the results for this date.

Once the calculation results are displayed, you may use your web browser's "Print" function to obtain a hardcopy of the results.

For locations above the Arctic Circle and below the Antarctic Circle, when a sunrise or sunset does not occur on the given day the program locates the local time and date of the most recent sunrise or sunset, and the next sunset or sunrise. When this occurs, the UTC fields will display "prior" or "next" information instead of the UTC times.

NOTE: For latitudes greater than 72 degrees N and S, calculations are accurate to within 10 minutes. For latitudes less than +/- 72° accuracy is approximately one minute. See Solar Calculation Details for further explanation.

olar Computer provides an easy way to compute sunrise and sunset times, and some other useful values, for any date and geographical location.

This version of Solar Computer is the most recent in a series of programs I have written over the years to provide a variety of useful solar computations. This version is written in JavaScript and replaces an older Java page (archived here). I replaced the old version because many people have requested a more flexible data source that can produce a table of values covering a year, rather than just one day. Also, over time there have been many changes in Java that had the side effect of preventing older programs from running properly. This is something that should never happen to a computer language, but it does happen, regularly, ultimately disabling any computer programs that are not rewritten over and over again to keep up with arbitrary changes in the language.

The new version is quite easy to use. Detailed documentation is provided below, but for those who want a quick result, here is how to proceed:

Longitude: Latitude: Positive in Western Hemisphere Positive in Northern Hemisphere Negative in Eastern Hemisphere Negative in Southern Hemisphere
