::I can't really comment on anything talked about by Brettpeirce, but I can say a few words about the "first day of the week" problem as seen by a computer programmer. It causes huge problems when your program displays a calendar because you have to take into account that Americans want it one way and most other people want it a different way. And supposedly simple things like scheduling an appointment "first work day next week" has a completely different result if it is done on a Sunday in the USA or on a Sunday in Europe. And then there's the problem of week numbers (used a lot in Europe but not so much in the USA). Week numbers depend on which week is designated as the first week of the year, which in most countries is defined as the first week with at least 4 days in the year. Now if January 3rd is Sunday, then in the USA it is the start of week 1, while in Europe it is the last day of the last week of the previous year (week 52 or 53). It's enough to drive you to drink (which is OK on Sunday some places but not others). --[[User:RenniePet|RenniePet]] ([[User talk:RenniePet|talk]]) 20:36, 5 September 2014 (UTC)

:::Oh, and then there are the incompatibilities in programming languages. American-developed computer languages like C and Basic and C++ and C# number the week days 0 - 6 meaning Sunday - Saturday. Meanwhile Java numbers week days 1 - 7 meaning Sunday - Saturday, except that the newest version, Java 8, has improved date/time facilities, and if you use them then week days are numbered 1 - 7 meaning Monday - Sunday. --[[User:RenniePet|RenniePet]] ([[User talk:RenniePet|talk]]) 20:52, 5 September 2014 (UTC)

::Contrary to ISO 8601, I think the week should start on Sunday for the sake of symmetry. [[Special:Contributions/188.114.99.189|188.114.99.189]] 01:18, 25 November 2015 (UTC)
 
  
 
I find instead interesting that he makes no mention of the seven notes, while mentioning other sets less ubiquitous --[[Special:Contributions/108.162.229.163|108.162.229.163]] 14:13, 5 September 2014 (UTC)
