Kodi Tsiku Line?

Monga awiri moyo tsiku lomwelo? Kodi kudumpha kuchokera lero kuti tsiku lotsatira popanda makina nthawi? Kodi mu dziko Chaka Chatsopano ndi loyamba la onse? Mayankho a mafunso amenewa ndi okhudzana ndi liwu monga Tsiku Line. Izi malire notional kukopedwa pa dziko lapansili ndi alekanitsa lomwe nthawi zosiyana za tsiku.

anataya tsiku

Monga amadziwika, ndi mawerengedwe a nthawi - ndondomeko si umboni. Kumakhudzana ndi malamulo lofunika dziko, ali zili kasinthasintha wa dziko lathuli padziko nguli ndipo zisinthe ake mozungulira dzuwa. chito izi zinali kuonekera, ndi maziko kudziwa nthawi kalelo. Komabe, ayenera kuganizira lamulo la dziko ndi kudziwa masiku olondola pamene muyenda mtunda chidwi anaonekera yekha mu 1521, pamene nsembe yake kuzungulira dziko Magellan. Gulu anafika pa nsonga ya kuchoka kwake, adapeza kuti Europe wakhala akukhala mu September 7, pamene logbook ali pachibwenzi September 6, - izo wasowa tsiku lina. Popeza zolembedwa pa chombo ikuchitika mosamala kwambiri, zolakwa Mwina anali otsika kwambiri. Atangochoka kufunsa maganizo a Europe kumvetsa pamene pa ulendo wa Magellan mbisoweka tsiku lina.

Tsiku Line: Tanthauzo

Dziko imazungulira ngati nguli kuchokera kumadzulo kupita kum'mawa. Choncho panyanja lotsogoleredwa ndi Magellan Pamilunguyo zosiyana. Iwo analambalala dziko kuchokera kummawa mpaka kumadzulo kuwona dzuwa wina ndi zosakwana ulendo anakumana mu Europe.

Chisokonezo chotero Kalanga sizinkachitika nthawi iliyonse munthu aganiza kuti ndipite kuzungulira dziko, Date Line zinachitikadi. Ndi pafupifupi kwathunthu pa meridian 180º ndi Malire pomwe nthawi ya tsiku ali yemweyo, koma kusintha kalendala tsiku. Mwachitsanzo, ngati kumadzulo kwa mzere pa kalendala May 18, ndiye kum'mawa - akadali 17. Pa nthawi yomweyo, ndi apo, ndi apo kuonera za nthawi yomweyo.

Malawi pa mapu

Mosiyana ndi ziro meridian Date Line nkomwe afika pa gawo dziko. Chifukwa cha zimenezi nthawi zambiri pamene muyenda kudutsa dziko alibe kuwonjezera kapena kuchotsera tsiku lina. Monga tanenera kale, chigawo chachikulu cha mzere chikugwirizana ndi meridian 180º. Izo zikugwirizana ndi mitengo iwiri kugwa pa dziko okha Antarctica. nthawi yoyamba malire kumbali ku meridian m'dera la m'dera kum'mawa kwa dziko lathu. Ndiye Date Line umadutsa Pacific Ocean, kuswa ndi Bering Strait. Kum'mwera kwa malire ake kumbali ku meridian 180º: izo masiketi kumadzulo Aleutians. Kenako Tsiku Line umadutsa madzi a nyanja yaikulu ya Earth. Yotsatira kwambiri kupatuka inali ku zilumba za Samoa, Fiji, Tongatapu, Chatham, Kermadec. Mfundo m'dera izi zikuchitika kum'mawa kwa meridian kenako kwa iye kum'mwera kwa New Zealand.

malire zosakhalitsa ukugawa Diomede Island mu Bering Strait. Mtunda pakati pa iwo ndi makilomita anayi okha. Pamene chisumbu Kruzenshtern a United States, komabe nthawi zonse, "dzulo", mu Ratmanova chilumba, m'dziko la Russia, kale "lero".

ulamuliro

Kusintha masiku ikhale pa mphambano za mzere. Ngati chimachititsanso m'chombo kuchokera kummawa mpaka kumadzulo, gulu lake ayenera kuwonjezera chiwerengero cha kalendala pa wina. Pankhani ya kusuntha izo amachepetsa zosiyana. Pa gawo, kumene nthawi malire a anakana, skirting zilumba za Oceania, timu ali ndi ufulu kusintha tsiku, kokha kuswa Meridian 180º, ngati ngalawayo si kupita limodzi mwa madoko, ndiye ndinu okonzeka kulunzanitsa ndi nthawi m'deralo.

Iwo likukhalira kuti pamene mukuwoloka pa mzere ku njira ina, mukhoza moyo kawiri tsiku lomwelo. Ena chibwenzi kufika basi ulendo pansi masiku kwambiri: laukwati, tsiku lobadwa.

Kupita malire

Mzere kusintha masiku mapu si nthawi zonse amaoneka ngati lero. Mu Philippines, pafupifupi kwa zaka za m'ma otsiriza kalendala anatembenuka pa mapepala mogwirizana ndi "American" kakyulasi. Choncho pa Tselebes chilumba chimene oyenerera pa longitude chomwecho, Pamilunguyo kusankha otchedwa Asia.

Alaska kalendala maloboti ndi nthawi ya dziko limene linali: kuti 1867 ndi Russia, ndiyeno - ndi United States. Chisamoa chilumba kawiri anasintha njira yake mawerengedwe malinga ndi zosoŵa za malonda. Mu 1892, pamene mwachangu malonda ndi United States, anaganiza kuti kayendedwe zosakhalitsa malire mpaka kumadzulo. Anthu a m'dziko chaka chomwecho kawiri anakumana mbandakucha July 4. patapita zaka, ndi pang'ono, mu 2011, anapita patsogolo asapita malonda ndi dera Asia-Pacific. Mayiko Tsiku Line anagwidwa kum'mawa kwa chilumbachi. Chifukwa cha chaka chino pambuyo December 29 msanga 31th.

Amene ali woyamba mu dziko kukondwerera Chaka Chatsopano?

A kupatuka kwambiri mzere wa meridian pafupi equator chifukwa chosankha cha boma la Kiribati mu 1995 kuonetsetsa kuti Islands Line watsopano nthawi zone. Chifukwa cha ichi unali wamphamvu kwambiri. Kiribati analigaŵa m'zigawo ziwiri: panthawiyo, monga munthu pa njira kalendala Mwachitsanzo, June 14, pa zina zinali 15.

Ndi pa zilumba za Line kale kuposa kwina kulikonse mu dziko, tsiku kwatsopano kumayambika. Chiwerengero cha m'dera koyamba pa January 1. Mfundo yomaliza wachititsa chochititsa manyazi ndi chopusa makamaka pakati pa anthu a zilumba New Zealand ndi Tonga. Iwo anali akupita kukakumana ndi Millennium choyamba, koma mapangidwe woyendera nthambi yatsopano nthawi, osauka iwo mwayi.

Pakati pake penipeni, kusintha mzere okha notional malire masiku. Pa maziko ake sali malamulo zilizonse. mzere lakonzedwa chomasuka kulankhulana lonse. Kusintha kuchokera tsiku lina kufikira pamene wina kudutsa malire zimenezi zikufanana ndi nthawi kutembenuka mu kusintha kwa masana kupulumutsa nthawi. zinthu zimenezi kungathandize munthu ikukhudzana m'gulu lawo kapena ntchito njira dziko, koma mwachindunji kwa iwo satsatira.
