In 2136 B.C.E. China had an eclipse.

The Imperial Court astronomers Hsi and Ho were executed for not predicting it.

An Ancient Poem describes the incident.

 Here lies the bodies of Hsi and Ho,

Whose fate, though sad, was visible:

Being killed because they did not spy

 Th’ eclipse which was invisible

Form A - U.S. Cities or Towns

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

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:
Latitude:
Time Zone:

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.
