Re: US vs. European Date Notation

Why do > Americans write dates as "December 31, 1999" while Europeans write "31 > December 1999", etc.? Why are in East Asia Bigendian dates more common? I wouldn't know the why, but Hungary is also bigendian. Not so surprising, in the names the christian name also follows the family name, so you have the "Street Chopin Frederic" (loosely translated). dik -- dik t. winter, cwi, kruislaan 413, 1098 sj amsterdam, nederland, +31205924131 home: bovenover 215, 1025 jn amsterdam, nederland; http://www.cwi.nl/~dik/

Proposed change to daylight-saving time in US
by Alex LIVINGSTON Jan. 28, 1999

Jan. 28, 1999

Exceptionally, I didn't find out first about this on this list! Below is a quote from a posting to the only other discussion list I subscribe to, CALNDR-L: At 19:43 -0600 1999-01-15, Bill Spencer wrote: >There is a bill to move Daylight Savings Time start from >April to March (1st Sunday of either). It was introduced by >Rep. Bill McCollum on 1999-01-06, and referred to the House >Committee on Commerce. >(http://thomas.loc.gov/cgi-bin/bdquery/z?d106:h.r.00177:) > >I happened upon this when looking through the main House of >Representatives web site (http://www.house.gov/) The bill actually calls it "Daylight Savings Time", when I thought we'd settled on "daylight-saving time" (or the same without the hyphen). At risk of inciting the wrath of some subscribers to the list, I'll dare to comment that this would be a very good northern-hemisphere standard, because (1) it means there are the same number of weeks (34) of daylight-saving time in every year, (2) the times of sunrise at the beginning and end of the period are close over a range of latitudes that covers practically all the population which might be affected (sun rises later in the high 20s north by about the same amount at the beginning than the end as it does earlier at the beginning than the end in the high 50s north), and (3) except in leap years starting on Thursdays, the start date is the Sunday of ISO week 9 and the end date is the Sunday of ISO week 43.

UK timezones
by pla＠sktb.demon.co.uk Jan. 20, 1999

Jan. 20, 1999

Since May 1994, one small part of mainland Britain has been running on a different timezone from the rest of the UK. The exception is Cheriton Terminal, the rail terminal at the UK end of the Channel Tunnel (run by the Eurotunnel Concession) at Cheriton, Folkestone, Kent. Cheriton Terminal runs on Concession Time (abbreviation CT) in winter and Concession Time (abbreviation CT) in summer. You might think the names and abbreviations are confusing and stupid, I couldn't possibly comment. CT is formally defined to be equivalent to French Civil Time. So at present, given the way the EU timezone rules operate and the fact that the French have not yet persuaded the EU to let them abandon daylight savings time, CT is one hour ahead of GMT in winter and one hour ahead of BST in summer. This information came via Clive Feather of Demon Internet who puzzled many Demon Internet users by asking which part of the UK was in a different timezone. It goes without saying that Clive is a rail enthusiast... --Paul
