Weeks in Daylight Saving Time
by Hank W. June 8, 2014

June 8, 2014

I just answered a question on Wiki Answers regarding how many weeks are in Daylight Saving Time. I dont know if any of you ever figured this out, so I thought some of you might find this interesting. Hank W. of Austin The duration of Daylight Saving Time (a.k.a. Summer Time) ranges from a low of 12 weeks in Fiji to a high of 34 weeks in North America and Chile (for reference, 3 months = 13 weeks, 6 months = 26 weeks, and 9 months = 39 weeks).... 34 weeks/year : * United States * Canada * Cuba * Haiti * Bermuda * Bahamas * Turks & Caicos * part of Greenland * Saint-Pierre & Miquelon * parts of Mexico 33 or 34 weeks/year : * Chile * Easter Island * part of Antarctica 30½ or 31½ weeks/year in Israel 30 or 31 weeks/year : * Europe, except Russia, Belarus and part of Ukraine * Azerbaijan * Turkey * Cyprus * Jordan * Lebanon * Syria * Namibia * most of Greenland * Azores * Canary Islands * Madeira Islands 29 or 30 weeks/year in most of Mexico 27 or 28 weeks/year : * New Zealand * Chatham Islands * Samoa * part of Antarctica 26½ weeks/year in Iran 26 or 27 weeks/year in Australia 25½ to 31 weeks/year in Morocco and Western Sahara 25 or 26 weeks/year in the Palestinian Territories 24 or 25 weeks/year in Paraguay 22 or 23 weeks/year in Uruguay 17½ to 22 weeks/year in Egypt 17 to 19 weeks/year in Brazil 12 or 13 weeks/year in Fiji

Yacht crew member killed after daylight-saving error
by Paul Eggert June 5, 2014

June 5, 2014

Here's a sobering reminder of one of the downsides of daylight saving time. Last month the Australian Transport Safety Bureau published its investigation into a fatal accident on 2013-02-08 at 13:45 +1100, as the motor yacht Calliope transited the Glebe Island Bridge in Rozelle Bay, Sydney Harbour. When the ship's master calculated tidal conditions for the transit, he determined that low tide would be at 13:20 local time. However, he forgot to allow for daylight saving time, and the actual low tide was at 14:20. The miscalculation contributed to a botched transit; as the crew positioned a fender to control contact with the bridge structure, an assistant engineer was caught between the yacht's fashion plate and a bridge-mounted fender, was pulled overboard, and died. Crane E. Crewman crushed to death in yacht crash after captain misjudged tide times when the clocks changed.

2014 DST changes in Egypt, again
by Imed Chihi June 5, 2014

June 5, 2014

Hi all. We have finally "located" a precise official reference about the DST changes in Egypt. The Ministers Cabinet decision is explained at http://www.cabinet.gov.eg/Media/CabinetMeetingsDetails.aspx?id=347 For some reason, this (Arabic) site is not accessible outside Egypt, but the page says: "وفيما يتعلق بالتوقيت الصيفى، فمن المقرر أن يبدأ العمل به فى تمام الساعة الثانية عشرة مساء اليوم الخميس 15/5/2014، على أن يتم وقف العمل به فى الساعة الثانية عشر مساء يوم الخميس 26/6/2014، ويعاد العمل بالتوقيت الصيفى مجدداً عقب انتهاء شهر رمضان،وذلك فى تمام الساعة الثانية عشر مساء يوم الخميس "31/7/2014. .. which translates into: "With regard to daylight saving time, it is scheduled to take effect at exactly twelve o'clock this evening, Thursday, 15 MAY 2014, to be suspended by twelve o'clock on the evening of Thursday, 26 JUN 2014, and re-established again at the end of the month of Ramadan, at twelve o'clock on the evening of Thursday, 31 JUL 2014." This statement has been reproduced by other (more accessible) sites: 1. http://elgornal.net/news/news.aspx?id=4699258 2. http://www.masrawy.com/news/egypt/politics/2014/may/15/5901668.aspx?ref=mor… 3. http://dostorasly.com/news/view.aspx?cdate=15052014&id=7e25a82b-6e9e-473a-8… 4. https://www.facebook.com/Egyptian.Cabinet.Of.Ministers/photos/a.20213898979… Since release 2014c was based on the assumption that the DST suspension would take place on 28 JUN 2014, I think that we'll need to make yet another adjustment to Africa/Cairo. -Imed
