Ano, letos o den d\u0159\u00edve ne\u017e v “u\u010debnicov\u00e9m term\u00ednu” 21. b\u0159ezna. Dnes, zat\u00edm co v\u011bt\u0161ina z v\u00e1s spala , ve 4:06 nastala jarn\u00ed rovnodennost a za\u010dalo astronomick\u00e9 jaro.<\/h6>\n

Dny se st\u00e1le prodlu\u017euj\u00ed, u\u017e od zimn\u00edho slunovratu a bude to tak a\u017e do letn\u00edho slunovratu 20. \u010dervna 2024. Dne\u0161n\u00ed den a noc budou p\u0159ibli\u017en\u011b stejn\u011b dlouh\u00e9. A pro\u010d jen p\u0159ibli\u017en\u011b? Proto\u017ee slune\u010dn\u00ed kotou\u010d nen\u00ed bodov\u00fd, nav\u00edc se jeho paprsky v na\u0161\u00ed atmosf\u00e9\u0159e oh\u00fdbaj\u00ed. V dne\u0161n\u00ed den \u201erovnodennosti\u201c tak bude Slunce viditeln\u00e9 nad obzorem p\u0159ibli\u017en\u011b 12 hodin a 8 minut. A tak s p\u0159ihl\u00e9dnut\u00edm k v\u00fd\u0161e uveden\u00fdm skute\u010dnostem se rovnodennosti nejv\u00edce p\u0159ibl\u00ed\u017eila ned\u011ble 17. b\u0159ezna, kdy m\u011bl den i noc stejnou d\u00e9lku, tedy 12 hodin.<\/p>\n

Mnoz\u00ed z n\u00e1s jsme se ve \u0161kole u\u010dili, \u017ee jarn\u00ed rovnodennost nast\u00e1v\u00e1 21. b\u0159ezna. To u\u017e ale neplat\u00ed (zkontrolujte d\u011btem u\u010debnice ). Ve 21. stolet\u00ed se tak naposledy stalo v roce 2011, znovu se tak stane a\u017e v roce 2102. Za zm\u011bnu data mohou p\u0159estupn\u00e9 roky. Zat\u00edmco my m\u00e1me v kalend\u00e1\u0159i 365, v p\u0159\u00edpad\u011b p\u0159estupn\u00e9ho roku 366 dn\u016f, Zem\u011b kolem Slunce ale ob\u011bhne za 365 dn\u00ed, 5 hodin a 49 minut. To znamen\u00e1, \u017ee ka\u017ed\u00fd rok se \u010das za\u010d\u00e1tku nap\u0159. jarn\u00ed rovnodennosti posouv\u00e1 o 5 hodin a 49 minut a ka\u017ed\u00fd \u010dtvrt\u00fd rok to zase vrac\u00edme o 24 hodin nazp\u011bt. A letos jsme 29. \u00fanor m\u011bli . Vz\u00e1cn\u011b m\u016f\u017ee jarn\u00ed rovnodennost nastat i 19. b\u0159ezna \u2013 posledn\u00ed v roce 1796, p\u0159\u00ed\u0161t\u00ed v roce 2048.<\/p>\n

P\u0159ejeme v\u0161em kr\u00e1sn\u00e9 jaro .
