Yintoni na Date Line?

Njengoko kabini-baphile suku? Indlela esuka namhlanje ukuya kusuku olulandelayo ngaphandle umatshini ixesha? Apho ehlabathini Unyaka Omtsha wokuqala kuyo yonke? ukuba iimpendulo zale mibuzo enxulumene ixesha ezifana Date Line. Le umda eziqingqiweyo azotywe zomphezulu komhlaba kwaye esahlula ummandla apho ixesha yahlukile yangathi yimini.

ngosuku ezilahlekileyo

Njengoko yaziwa, ekubaleni ixesha - le nkqubo ayikho abstract. Elidityaniswe kunye nemithetho engundoqo cosmic, zibonakaliswa ukujikeleza umhlaba wethu axis yayo revolution yayo ijikeleza ilanga. Ezi iipateni yabonakala, isiseko ogcina kumaxesha amandulo. Noko ke, imfuneko ukuqwalasela isindululo ngenxa yomhlaba kanye ukuqikelela imihla ezichanekileyo xa uhambisa kumgama encomekayo wabonakala kuphela ngo-1521, xa senziwa bakhe uhambo ehlabathini jikelele Magellan. Iqela safika kwindawo ngokumka kwakhe, wafumanisa ukuba iYurophu sele abahlala ngoSeptemba 7, ngoxa kwi-logbook libhalwe ngoSeptemba 6, - ukuba unyamalale ngenye imini. Ekubeni uxwebhu uthiwe wenziwe ngocoselelo olukhulu, amathuba wemposiso ephantsi kakhulu. Kungekudala emva sokubuza iingqondo yaseYurophu ukuqonda apho ebudeni uhambo Magellan wanyamalala ngenye imini.

Umhla Line: Inkcazo

Umhlaba lijikeleza phezu axis wayo ukusuka entshona ukuya empuma. Ngoko ke omkhulu elikhokelwa Magellan ngqo icala. Ke weza umhlaba ukusuka empuma kuye entshona ukubona omnye ukuphuma ingaphantsi uhambo wadibana eYurophu.

Ngokwe- ukudideka lilishwa enjalo akuzange kwenzeke lonke ixesha umntu ugqiba ukuya ehlabathini lonke, Umhla Line lwaqhutywa. Kuyinto phantse ngokupheleleyo cwaka 180º kwaye umda apho ixesha losuku iyafana, kodwa ukutshintsha umhla wekhalenda. Umzekelo, ukuba ngasentshonalanga umgca kwikhalenda ngoMeyi 18, ngoko empumalanga - nangoku 17. Ngelo xesha, yaye apho, yaye kukho ubukele ibonisa malunga ngexesha elifanayo.

Indawo yokuhlala kwimephu

Mu kuya kwa nshita zero okuyi Umhla Line ngenkankulu ukhwela kummandla komhlaba. Ngenxa yoko ixesha elininzi xa ukunqumla umhlaba musa ukuba ukudibanisa okanye ukuthabatha ngenye imini. Njengoko sele kukhankanyiwe, inxalenye engundoqo komgca ingqamana ithe cwaka 180º. Idibanisa izibonda ezimbini owa phezu komhlaba kuphela Antarctica. umda okokuqala kuphambuka ithe cwaka kwingingqi kummandla okwimpuma yelizwe lethu. Emva koko Date Line enqamleza lwePasifiki, ukuqhekeza i wethu Strait. Ukuya ezantsi emdeni wakhe kwakhona kuphambuka ithe cwaka 180º: kuyo iziketi ngasentshonalanga Aleutians. Okulandelayo Date Line udlula amanzi olwandle inkulu Umhlaba. Ukuphambuka ebalulekileyo olulandelayo ibekwe kwi kwiziqithi Samoa, eFiji, Tongatapu, Chatham, Kermadec. Umgca kule ndawo kwenzeka empuma ithe cwaka emva koko wabuyela kuye ezantsi of New Zealand.

umda okwethutyana iyahlula Diomede Island kwi wethu Strait. Umgama phakathi kwabo ngumgama oziikhilomitha ezine kuphela. Xa siqithi Kruzenshtern besive eUnited States, lusaqhubeka, "izolo", e Ratmanova esiqithini, lalo eRashiya, sele "namhlanje".

mthetho

Tshintsha kwemihla kufuneka senziwe kwi ekudibaneni kwe emgceni. Ukuba osondela ukusuka empuma kuye entshona, iqela lakhe kufuneka ukwandisa inani elikwi omnye. Kwimeko iyisa awusafuni kwicala elahlukileyo. Kwi ceke, apho ixesha umda ziyekwe, ezigudle iziqithi Oceania, eli qela unalo ilungelo lokutshintsha umhla, beqhekeza kuphela Meridian 180º, ukuba inqanawa ayikho ukuya kwelinye zamazibuko, oko kukuthi, ukulungele ukuvumelanisa ne ixesha lendawo yakho.

Kubonakala ukuba xa ukunqumla umgca kwicala elithile, unako ukuphila kabini loo mini. Ezinye romance ufika nje olo hambo phantsi imihla ebalulekileyo: Lusuku lomtshato, lokuzalwa.

Moving imida

Imihla utshintsho Line mephu azisoloko khangela ngathi namhlanje. KwiiPhilippines, phantse ukuya phakathi kwiminyaka yokugqibela eli khalenda wabhukuqa amaphepha ngokungqinelana calculus "American". Ngaloo ndlela Tselebes ndisesiqithini zilahlwa kwi owehlayo enye, mayilandelwe kukhetho ebizwa ngokuba yi-Asia.

ikhalenda Alaska ingqanyaniswe ixesha kweli lizwe apho ngeyabo: ukuya 1867 ne-Russia, uze - kunye eUnited States. BaseSamoa island zatshintsha kabini indlela yayo yokubala ngokungqinelana neemfuno kurhwebo. Ngowe-1892, xa ngenkuthalo ekurhwebeni eUnited States, kwagqitywa ekubeni intshukumo okwethutyana kwimida ukuya ngasentshona. Abahlali lizwe kulo nyaka ndadibana kabini Julayi 4 isifingo. Kwinkulungwane kamva, kancinane, ngowe-2011, wafika kuqala ubudlelwane borhwebo kunye kummandla Asia-Pacific. International Date Line wafuduselwa ukuya ngasempuma siqithi. Ngenxa kulo nyaka emva kokuba December 29 eze nangoko 31th.

Ngubani na kuqala ehlabathini ukuba babhiyozele Unyaka Omtsha?

A ecaleni ebonakalayo kumnombo ithe cwaka kufutshane ikhweyitha ngenxa ngesigqibo Government of Kiribati ngo-1995 ezabelwe Line Islands izowuni yexesha elitsha. Isizathu sokuba oku gqitha ezinzima. Kiribati yahlulwa imimandla emibini: ngelo xesha, njengoko kwi enye indlela kwikhalenda, umzekelo, Juni 14, kwelinye kwaba 15.

It is on the Line Islands ngaphambili kunayo nayiphi na enye ehlabathini, usuku olutsha luqalisa. Inani labantu kulo mmandla wadibana ngoJanuwari 1. Loo nto yokugqibela kuye kwabangela Ndilicukuceze ethile phakathi kwabantu of New Zealand kunye Tonga iziqithi. Babesiya ukuhlangabezana Millennium yokuqala, kodwa ukuyilwa kwizowuni yexesha entsha, ndayihluthwa kuwo thuba.

Xa ezingundoqo zalo, iinguqu bamacandelo imihla umda eziqingqiweyo kuphela. ezihleli noseko lwalo hayi nayiphi na imithetho yemvelo. Umgca yenzelwe lula nonxibelelwano lwamazwe ngamazwe. Ukutshintsha ukusuka kumhla omnye ukuya komnye ngexesha kuwela le umda liyafana ukuguqulwa xesha kwi inguqu ukuba emini ixesha ukonga. Le misebenzi incedisa umntu ukubalisa intshukumo okanye umsebenzi kunye neenkqubo yesiqalo, kodwa ngqo kubo musa landela.
