Okay, I was confused about the terminology, base chronology. There are still a couple of points I still don't fully understand: The proposal now says that the gregorian and julian chronologies are both proleptic. Do I interpret correctly that this means that in the gregorian chronology, the day before 1582-10-15 is 1582-10-14, not 1582-10-04? In the julian chronology, is there a gregorian reform after 1582-10-04? Do the gregorian and julian chronologies have a year zero? -- John Foerch _______________________________________________ Scheme-reports mailing list [email protected] http://lists.scheme-reports.org/cgi-bin/mailman/listinfo/scheme-reports
