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:

• Decide on which form to use. If you want a table for cities or towns in the U.S. or its territories, use Form A below. For other locations, use Form B below.
• Enter the year for which the table is desired.
• Select the table type (sunrise/sunset, moonrise/moonset, etc.) from the pop-up list in the form that you are using.
• Specify the location of interest using the fields provided on the form.
• Click the "Compute Table" button at the end of the form to compute the table. The table will provide the data requested in local standard time on a 24-hour clock; for example, 1836 means 6:36 p.m., local standard time.
• Be sure to read Notes section (on this page beyond the two forms) for an explanation of the items in the table.

Form A - U.S. Cities or Towns

Specify year, type of table, and place:

Year:   Type of table: sunrise/sunset moonrise/moonset civil twilight nautical twilight astronomical twilight

State or Territory:   Alabama Alaska American Samoa Arizona Arkansas California Colorado Connecticut Delaware District of Columbia Florida Georgia Guam Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota N. Mariana Islands Ohio Oklahoma Oregon Pennsylvania Puerto Rico Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virgin Islands Virginia Washington West Virginia Wisconsin Wyoming

City or Town 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". You need only enter as many characters as will unambiguously identify the place.

Form B - Locations Worldwide

Specify year, type of table, and place:

Year:   Type of table: sunrise/sunset moonrise/moonset civil twilight nautical twilight astronomical twilight

Place Name Label:  

The place name you enter above is merely a label for the table header; you can enter any identifier, or none (avoid using punctuation characters). The data will be calculated for the longitude and latitude you enter below.

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 Internet Explorer, click on File then Save As...), then use your favorite word processor or text editor to print it.

How to Import the Table into a Spreadsheet

Open your favorite text editor, then copy the numerical part of the table (i.e., do not copy the table headings) from your browser and paste it into the text editor. Save the data as a text file.

In Excel 2003, click Data on the menu bar, then Import External Data, then Import Data. Select your saved text file. Choose fixed width in the dialog box. [In Excel 2004 for Mac, the commands are Data -> Get External Data -> Import Text File]

In Excel 2007, click Data on the menu bar, then From Text. Select your saved text file. Choose fixed width in the dialog box.

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
