this question has certainly came up before. Every time I deal with a date and the date class, I come to the point where I wonder if only dates from 1.1.1970 can be processed correctly by the class (leap years, weeks, weekdays etc.). I have an application where dates around 1100 or 223 B.C. are also processed (dates before the introduction of the Gregorian calendar). Can the class also handle this "correctly"?
Maybe someone from Xojo @Paul L can answer the question explicitly and include a clear internal reference in the documentation. I find this 1970 date confusing.
