A great help for those who spend Easter carrying a tent around in the mountains. Clearly, a calendar that doesn't accomodate the needs of such an important group isn't worth the van Gogh reproductions. -- Trond Engen

Which is why Easter and Passover rarely coincide -- we happen to have had a spate of coincidence in recent years, but that'll soon be over. > What could be simpler? The Muslim calendar -- no intercalated months, and no connection with the solar year. So Ramadan drifts through the seasons.

What about Thor's Day, or Thursday? I don't like it where its at. Can we move it to Friday? So I get that Friday feelin a lot earlier. And while you are at it, can you switch Monday with Wednesday so that Monday feels more like a Wednesday to avoid the dreaded Monday mornin feelin. > 2.
