V minul\u00e9 anket\u011b jsme se v\u00e1s zeptali na moment\u00e1ln\u011b relativn\u011b \u017ehav\u00e9 t\u00e9ma v Evrop\u011b a to st\u0159\u00edd\u00e1n\u00ed letn\u00edho a zimn\u00edho \u010dasu. Na z\u00e1klad\u011b evropsk\u00e9ho referenda se EU rozhodla zru\u0161it na\u0159\u00edzen\u00ed o st\u0159\u00edd\u00e1n\u00ed \u010dasu a bylo by tak na jednotliv\u00fdch zem\u00edch, zda tuto tradici zachovaj\u00ed, \u010di zda p\u0159ejdou na nem\u011bnn\u00fd \u010das – a ani tady nepanuje shoda, jeliko\u017e \u010d\u00e1st zem\u00ed chce z\u016fstat u letn\u00edho \u010dasu, zat\u00edmco druh\u00e1 u zimn\u00edho.<\/p>\n

Letn\u00ed \u010das byl poprv\u00e9 zaveden v roce 1916. V \u010ceskoslovensku se pravideln\u011b \u010das st\u0159\u00eddal od roku 1979. Ke zm\u011bn\u011b doch\u00e1z\u00ed v\u017edy posledn\u00ed b\u0159eznov\u00fd v\u00edkend (v ned\u011bli r\u00e1no se \u010das posune ze 2 na 3 h a nast\u00e1v\u00e1 letn\u00ed \u010das) a posledn\u00ed \u0159\u00edjnov\u00fd t\u00fdden (v ned\u011bli r\u00e1no se \u010das posune ze 3 h zp\u011bt na 2 h a nast\u00e1v\u00e1 zimn\u00ed \u010das). A\u017e do roku 1996 nast\u00e1val zimn\u00ed \u010das o m\u011bs\u00edc d\u0159\u00edve, tedy posledn\u00ed v\u00edkend v z\u00e1\u0159\u00ed.<\/p>\n

Co konkr\u00e9tn\u011b by zm\u011bna na stejn\u00fd \u010das cel\u00fd rok p\u0159inesla? Pod\u00edvejme se na to \u010dist\u011b z pohledu v\u00fdchod\u016f a z\u00e1pad\u016f Slunce, tedy toho, co asi nejv\u00edce lid\u00e9 registruj\u00ed. Pod\u00edvejme se na \u010dasy v\u00fdchodu a z\u00e1padu Slunce v jeden den v prosinci a jeden den v \u010dervnu a srovnejme v\u0161echny mo\u017en\u00e9 alternativy (\u010dasy jsou orienta\u010dn\u00ed pro lokalitu Brna).<\/p>\n\n\n\n\n\n\n\n

Co z v\u00fd\u0161e uveden\u00e9ho vypl\u00fdv\u00e1. Pokud by se p\u0159e\u0161lo na permanentn\u00ed zimn\u00ed \u010das, v l\u00e9t\u011b by ji\u017e nebylo tak dlouho sv\u011btlo ve\u010der. Zat\u00edmco nyn\u00ed v nejdel\u0161\u00ed den zapad\u00e1 Slunce a\u017e po 21 h (a je\u0161t\u011b n\u011bjakou dobu je sv\u011btlo), nyn\u00ed by to bylo ji\u017e kr\u00e1tce po 20 h. V zim\u011b by k \u017e\u00e1dn\u00e9 zm\u011bn\u011b nedo\u0161lo (proto\u017ee ji\u017e te\u010f v zimu zimn\u00ed \u010das je). Pokud by byl zaveden st\u00e1l\u00fd letn\u00ed \u010das, v l\u00e9t\u011b by nedo\u0161lo k \u017e\u00e1dn\u00e9 zm\u011bn\u011b oproti st\u00e1vaj\u00edc\u00edmu stavu, naopak v zim\u011b by se rozedn\u00edvalo v nejkrat\u0161\u00ed den a\u017e p\u0159ed 9 h, ale zase by Slunce zapadalo a\u017e kr\u00e1tce p\u0159ed 17 h, oproti st\u00e1vaj\u00edc\u00ed 16 h.<\/p>\n

Ob\u011b \u0159e\u0161en\u00ed tedy maj\u00ed sv\u00e1 pro a proti. Zimn\u00ed \u010das by znamenal d\u0159\u00edv\u011bj\u0161\u00ed tmu v l\u00e9t\u011b, co\u017e m\u016f\u017ee v\u011bt\u0161ina lid\u00ed pova\u017eovat za nev\u00fdhodu, naopak ale by znamenal d\u0159\u00edve sv\u011btlo r\u00e1no v zim\u011b, co\u017e tak\u00e9 lze pova\u017eovat za plus. Letn\u00ed \u010das by zachoval d\u00e9lku sv\u011btla v l\u00e9t\u011b, ale v zim\u011b by znamenal v\u00fdchod Slunce a\u017e p\u0159ed 9 h rann\u00ed.<\/p>\n

A jak dopadla anketa? Celkem bylo zaznamen\u00e1no 58 platn\u00fdch hlas\u016f. Nejvy\u0161\u0161\u00ed po\u010det, 24 hlas\u016f (42 %) hlasuj\u00edc\u00edch by si p\u0159\u00e1lo ponechat pouze zimn\u00ed \u010das. O 3 hlasy m\u00e9n\u011b, tedy 21 hlas\u016f (36 %) dostala mo\u017enost zachov\u00e1n\u00ed pouze letn\u00edho \u010dasu. 10 hlasuj\u00edc\u00edch (17 %) by si p\u0159\u00e1lo zanechat st\u00e1vaj\u00edc\u00ed stav, tedy st\u0159\u00edd\u00e1n\u00ed letn\u00edho a zimn\u00edho \u010dasu a 5 % hlasuj\u00edc\u00edch (3 hlasy) je to jedno.<\/p>\n
