which day of the week

[bplus]

I don't think Eric and Pete are accounting for the change in 1582 as macalwen has.

I tried to find the first day of Jan 1, 0 AD and Pete says Sunday because Eriks say Sunday I bet and when I disable macalwen's check for years less than 1, he gives me Friday. That is the way to start off an era, going into a weekend!
