Notes
- 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.
- For information on the definitions of terms used, see Rise, Set, and Twilight Definitions or Phases of the Moon and Percent of the Moon Illuminated in FAQ.
- Please see Astronomical Data Used for Litigation if you are interested in using for legal purposes the data produced by this service.
- If you need rise/set or twilight times for a series of dates for a location, use our rise/set table program, which computes a one-page table covering an entire year.
- The output times will be on a 12-hour clock (with "a.m." or "p.m." listed). 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 is implemented only for years 1967 and later, in accordance with the Uniform Time Act of 1966 and subsequent legislation. Daylight time is not used for places currently exempt from it.
