I edited your message down to the following: is it OK if I include this in a future revision of the `europe' file? # From Chris Carrier <72157.3334@CompuServe.COM> (1996-12-02): # On 1929-10-01 the Soviet Union instituted an ``Eternal Calendar'' # with 30-day months plus 5 holidays, with a 5-day week. # On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the # Gregorian calendar while retaining the 6-day week; on 1940-06-27 it # reverted to the 7-day week. With the 6-day week the usual days # off were the 6th, 12th, 18th, 24th and 30th of the month. # (Source: Evitiar Zerubavel, _The Seven Day Circle_) This is OK; I didn't know how much material to include, because the topic of discussion of the list is the clock, not the calendar, but Gregorian and the 5 and 6 day week experimental calendars were mentioned so I thought I should refine the data. I think the reason that the Russian Orthodox adhere to the Julian calendar, even today, is because Easter is getting steadily later under it. Easter is, after all, a spring festival, and late March in most of Russia is still snowy and very cold. By placing Easter in the date range April 4 - May 8 instead of March 22 - April 25 it's more springlike. Chris Carrier
