Sun or Moon Rise/Set Table for One Year


bar

Important!  Please read the Notes section.

This page provides a way for you to obtain a table of the times of sunrise/sunset, moonrise/moonset, or the beginning and end of twilight, for one year.

You can obtain a table for any location worldwide by following these simple steps:



Form A - Cities or Towns in the U.S.

Specify year, type of table, and place:

Type of table:

State or Territory:

Place Name:

The place name you enter above must be a city or town in the U.S. The place's location will be retrieved from a file with over 22,000 places listed. Either upper- or lower-case letters or a combination can be used. Spell out place name prefixes, as in "East Orange", "Fort Lauderdale", "Mount Vernon", etc. The only exception is "St.", which is entered as an abbreviation with a period, as in "St. Louis".


Form B - Locations Worldwide

Specify year, type of table, and place:

Type of table:

Place Name:  

The place name you enter above is used only in the table header; you can enter any identifier, or none (do not use punctuation characters).

Longitude:     east   west   degrees   minutes

Latitude:     north   south   degrees   minutes

Time Zone:     hours   east of Greenwich   west of Greenwich

For locations that require it, the time zone can be entered in hours and a fraction. For example, for locations in India, the time zone may be entered as 5.5 hours east of Greenwich. The time zone field can accommodate up to five characters.

How to Print the Table
The table is 134 characters wide, so to print it you must use landscape orientation and 8-point (smallest) type. Consult your browser's documentation for details on how to change the font/text size. An alternative scheme is to save the table to a file on your computer (for example, in Netscape, click on File then Save As...), then use your favorite word processor or text editor to print it.

Definitions
For information on the definitions of rise, set, and twilight, see Rise, Set, and Twilight Definitions in FAQ.

Time Zones
The times of the phenomena are presented in the standard time of the place requested, using the current time zone of the place. Standard time in time zones was introduced in the U.S. in 1883, but the time zone boundaries have evolved considerably since then, with places shifting from one zone to another. There is no attempt here to track such changes.

Daylight Time
Daylight time is not implemented in this program. When daylight time is in use, add one hour to the times listed in the table.

Legal Use of the Data in the Table
Please see Astronomical Data Used for Litigation if you are interested in using for legal purposes the data produced by this service.
