I kdy\u017e astronomie dala lidstvu p\u0159esn\u00fd \u010das, s p\u0159echodem na letn\u00ed \u010das (SEL\u010c), kter\u00fd n\u00e1s \u010dek\u00e1 v noci na z\u00edt\u0159ek, nem\u00e1 nic spole\u010dn\u00e9ho. Nepot\u0159ebujeme ho (stejn\u011b v\u0161e zaznamen\u00e1v\u00e1me ve sv\u011btov\u00e9m \u010dase UT). Letn\u00ed \u010das dnes ani nic neu\u0161et\u0159\u00ed, naopak jeho zav\u00e1d\u011bn\u00ed stoj\u00ed pen\u00edze a spoust\u011b lid\u00ed p\u0159echod dvakr\u00e1t ro\u010dn\u011b vad\u00ed. Jedn\u00e1 se \u010dist\u011b o administrativn\u00ed opat\u0159en\u00ed. Jen pozor, kdybyste se rozohnili, tak abyste nevzali \u00fatokem i zimn\u00ed \u010das. Ten toti\u017e neexistuje, resp. nen\u00ed u n\u00e1s v sou\u010dasnosti zaveden. V pr\u016fb\u011bhu roku u plat\u00ed st\u0159edoevropsk\u00fd \u010das SE\u010c a st\u0159edoevropsk\u00fd letn\u00ed \u010das SEL\u010c.<\/h6>\n

\"\"O zru\u0161en\u00ed st\u0159\u00edd\u00e1n\u00ed \u010dasu rozhodl v roce 2019 Evropsk\u00fd parlament. Proto\u017ee zem\u011b Evropsk\u00e9 unie se od t\u00e9 doby nedohodly, jak d\u00e1l a nic nenasv\u011bd\u010duje tomu, \u017ee se tak v bl\u00edzk\u00fdch letech stane – pokra\u010dujeme ve st\u0159\u00edd\u00e1n\u00ed \u010das\u016f v pr\u016fb\u011bhu roku. Tak\u017ee v\u00e1m p\u0159ejeme dobrou, i kdy\u017e o hodinu krat\u0161\u00ed noc.<\/p>\n

A jak to vlastn\u011b bude d\u00e1l? N\u011bkter\u00e9 st\u00e1ty se p\u0159ikl\u00e1n\u011bj\u00ed k trvale letn\u00edmu \u010dasu, jin\u00e9 by pokra\u010dovaly ve st\u0159\u00edd\u00e1n\u00ed \u010dasu a n\u011bkter\u00e9 se klon\u00ed ke st\u0159edoevropsk\u00e9mu \u010dasu, tedy tomu, kter\u00fd prob\u00edh\u00e1 v dob\u011b, kdy nen\u00ed nastaven ten letn\u00ed. Tato debata je pom\u011brn\u011b p\u0159ekvapiv\u00e1, proto\u017ee se nab\u00edzelo \u0159e\u0161en\u00ed vr\u00e1tit se k p\u0159\u00edrodn\u00edmu \u010dasu, kter\u00fd je symetrick\u00fd v\u016f\u010di v\u00fdchodu a z\u00e1padu Slunce a kter\u00fd odpov\u00edd\u00e1 na\u0161im fyziologick\u00fdm pot\u0159eb\u00e1m.<\/p>\n

V noci ze soboty 28. na ned\u011bli 29. b\u0159ezna si ve 2 hodiny v noci posuneme \u010das na 3. hodinu. Noc tak bude sice o hodinu krat\u0161\u00ed, zato zast\u00e1nci letn\u00edho \u010dasu a milovn\u00edci dlouh\u00fdch letn\u00edch ve\u010der\u016f budou slavit. Zhruba p\u011btina obyvatel s t\u00edm bude m\u00edt probl\u00e9m srovnat se v jejich \u010dasov\u00e9m rytmu. Ale nutno dodat, \u017ee za p\u00e1r dn\u00ed se to sprav\u00ed. Ale \u010dek\u00e1 je je\u0161t\u011b jedna zm\u011bna \u010dasu na podzim a budou to absolvovat znovu.<\/p>\n

Spolu s ji\u017e neexistuj\u00edc\u00edmi ekonomick\u00fdmi d\u016fvody pro zaveden\u00ed letn\u00edho \u010dasu postr\u00e1d\u00e1 st\u0159\u00edd\u00e1n\u00ed \u010dasu smysl a pokra\u010duje jenom proto, \u017ee se zem\u011b Evropsk\u00e9 unie nedok\u00e1\u017e\u00ed dohodnout. Na p\u0159em\u00fd\u0161len\u00ed, jak d\u00e1l a p\u0159edev\u0161\u00edm, jak spr\u00e1vn\u011b d\u00e1l, m\u00e1me zase n\u011bjak\u00fd ten \u010das. Kter\u00e1 volba je vhodn\u011bj\u0161\u00ed?<\/p>\n

N\u011bkte\u0159\u00ed p\u0159i\u0161li s n\u00e1padem ponechat letn\u00ed \u010das po cel\u00fd rok. Dlouh\u00e9 letn\u00ed ve\u010dery, zbyte\u010dn\u00e9 sv\u011btlo r\u00e1no, kter\u00e9 n\u00e1s, civilizovan\u00e9 a odcizen\u00e9 od d\u0159\u00edv\u011bj\u0161\u00edho \u017eivota sedl\u00e1k\u016f a hospod\u00e1\u0159\u016f, zbyte\u010dn\u011b bud\u00ed. Zn\u00ed to l\u00e1kav\u011b a leckdo pro to tak\u00e9 zved\u00e1 ruku. Probl\u00e9m ale nast\u00e1v\u00e1 ve druh\u00e9 \u010d\u00e1sti roku, v zim\u011b, kdy trval\u00fd letn\u00ed \u010das znamen\u00e1 v\u00edce tmy r\u00e1no, za\u010d\u00e1tek \u0161koly je\u0161t\u011b za tmy, p\u0159itom rann\u00ed sv\u011btlo je pro n\u00e1\u0161 organismus naprosto z\u00e1sadn\u00ed. Na tom se shoduj\u00ed fyziologov\u00e9 nap\u0159\u00ed\u010d Evropou i cel\u00fdm sv\u011btem.
