John and others,

Maybe I'm being dense, but isn't the variation of the equation of time with longitude masked (or at least complicated) by the similar variation, from one year to the next, due to our use of a 365-day calendar and occasional leap year?

It's hard for me to imagine that the longitude deviation would ever need to be included in a sundial design. (But if one is observing a noon transit of the Sun in a specific year and calendar date for establishing a true north-south line, then it *would* be helpful.)

Hello All:
 
Does anybody know if there is a program, spreadsheet or website that will calculate EOT values corrected for specific longitudes in either a graph or a table?
