Emini - lena isikhathi malini? Isikhathi sosuku - ngosuku. AM - isikhathi

Isikhathi, njengoba wazi - yigama futhi kwezinye izimo, futhi Olwandisekayo. Thina zisetshenziselwa ulwahlukanise ziphenduka iminyaka, izinyanga, izinsuku, amahora, imizuzu namasekhondi. Kodwa elithi ezifana emini - lena isikhathi malini? It kuvela ukuthi impendulo yalo mbuzo akulula njengoba kubonakala efika kuqala. Futhi uma uthi ntambama - kungcono emini, ungenza iphutha. Ingabe lokhu kusho ukuthi leli gama njengoba relyativen, njengazo zonke vremyaischislenie womuntu? Nokho, yebo nangokuthi cha. Masizame ukufunda le nkinga kakhulu.

usuku

Ukuze siphendule lo mbuzo, "Emini - yinde kangakanani?", Kuyadingeka ukwazi esilinganisweni kuyini. Lokhu njalo lomkhathi kukhona kwezincazelo ngokusentshenziswa phakathi nosuku. Futhi ukwenza ihluke kanjani usuku noma usuku? Ngolimi lwesiNgisi, okuyinto, njengoba sazi, ukusebenza ezingaphezu kuka-Russian, lokhu Analogue kusichazamazwi. Umuntu osesilinganisweni emgwaqweni uthi ngosuku, okusho "usuku". Ukuze uthole azinabo notation izinsuku njengoba ukusetshenziswa leli gama eqonde kakhulu - amahora angu-24. ibinzana imini nobusuku futhi ezivamile. Ezilimini Slavic igama elithi "usuku" noma "Doba" livela egameni "umhlangano" futhi "ngokuhlanganyela". Ngakho, usuku luqala, noma ngemva-evutha kuhlwa noma entathakusa, okungukuthi, lapho kukhona amnyama kanye amahora emini. Emini, njengoba kusobala kusukela etymology yezwi, kuyinto phakathi nosuku.

usuku Solar futhi sidereal

Sasebenzisa ukucabanga ukuthi isikhathi iyunithi yakhiwa amahora amabili nane, kodwa izazi zezinkanyezi ukuhlukanisa phakathi kosuku elanga futhi sidereal, okuyizinto akulingani nomunye. Iplanethi yethu uzungeza kuma yayo amahora-eksisi 24, kodwa ngenxa ilanga ushukumisela ezinyakazayo esemkhathini Zomhlaba, ngakho ngosuku sidereal sithatha amahora amabili nantathu, imizuzu amahlanu nesithupha namasekhondi ezine. Kukhona okuthile abangacabanga ngakho! Ikakhulukazi njengoba Umhlaba ihamba ilanga Ukuboshelwa. Ukuze ulungise iphutha, njalo Disemba 31 noma 30 Juni esethula okuthiwa "nigxumagxume yesibili." Ukuze ubone ukuthi lokhu ntambama - lena isikhathi kangakanani - ku Observatory ye-Greenwich ngosuku we Vernal noma ngesikhathi sokulingana kwemini nobusuku ekwindla. Unqenqema engenhla inhlamvu yelanga kumelwe avuke ngaphezu komhlabathi at 6 ekuseni futhi ngokuphelele ebusweni at 6pm. A inkanyiso emini itholakala phakathi iphuzu esiphezulu lalingabonakali emkhathizwe - a zenith.

Imini nobusuku

Ekuphileni kwethu kwansuku zonke sivamile bamelele le miqondo emibili. Ngakho, sithi "usuku June 18", okusho ukuthi yonke inkathi isikhathi ezisukela amahora angu-0 kuya ku-23, imizuzu 59 no-59 imizuzwana. Kodwa ngaso sonke isikhathi imingcele usuku wakhonza phakathi kobusuku. AmaGreki asendulo, abaseGibhithe ngenhlupho abese Slavic yabalwa kusukela ekuqaleni entsha usuku entathakusa. Esikhathini lamaJuda, "Yamama", okusho suku luqala lapho isibhakabhaka zikhanyise wokuqala inkanyezi (okusho ukuthi ngemuva kwelanga). Iminonjana ngesikhathi esinjalo sokwenziwa ukubala kwaba ngo "Eves" e ngokugubha amaholide ezinkulu zenkolo, ngakho-ke kwakunzima uqhathanise amanani amabili. Emini - lena isikhathi malini? Kungaba amahora ayisithupha nesikhombisa. Ikakhulukazi ezindaweni ezinezinga lokushisa elithokomele emini incike zonyaka. Bese indlela ukunquma ntambama e-Arctic Circle, lapho ukukhanya kwethu ayinakuboniswa izinsuku?

Ukuhlala njalo isihlobo

Kunengqondo ukuphetha ngokuthi yonke into ilula. Ilanga emini imi-zenith, ie-ke ifinyelela ukuphakama esiphezulu esibhakabhakeni. Kwakhanya Ezindaweni zethu liphuma ngempela empumalanga kanye eningizimu kancane, futhi ihamba kanye onqenqemeni kwesibhakabhaka emini. Ngakho, uma ifinyelela ukuphakama esiphezulu futhi iqala ukuhamba kwayo ekupheleni, indawo yayo ingachazwa njenge ngokuqinile Southern. Enkabazwe, emini - lena lapho Ukukhanya kuyakhanya ilungelo phezu kwekhanda lakhe. Futhi Nenkabazwe eningizimu ngalesi sikhathi ilanga iyabonakala ngisho enyakatho. Isikhathi sosuku - usuku, ekuseni, kusihlwa nobusuku - iyahlukahluka kuye ngokuthi inkathi. Ehlobo uthola emnyama kamuva, endaweni ethile kukhona nobusuku obungamashumi mhlophe futhi ekuqaleni ebusika ebusuku yehla. Kodwa ntambama - kuba njalo. Ngalesi sikhathi, amathunzi kukhona emfushane (ukushona ezindaweni ezishisayo, ngokuvamile ukufihla ngaphansi kwezinyawo zenu), ngakho emini Kulula ukubala. Woza emhlabathini flat, bagqekeza lo phansi isikhonkwane mpo. Okulandelayo ukumisa nekhampasi. Lapho emthunzini isikhonkwane uyokhomba ncamashi eningizimu, yayisikhuphuka emini.

Yini evimbela ukuba yini ukuthola isikhathi esinembile

Konke theory. Yini eyokwenzeka uma singakhathali isinqumo kule eksperimenti lelula? Ake sithi esisichitha nakho kwethu Berdyansk (Ukraine). Umphumela zokuhlola lubonisa ukuthi lapho emini kwenzeka e amahora 11 nemizuzu engu-40. ETranscarpathia sibalo kugudlukela ngesigamu sehora ngakolunye uhlangothi - 12:30. Kungani emini on iwashi ayihambisani weqiniso zenith solar? Lapha e imithetho yemvelo ihlaselwe yezakhi inqubomgomo. Ukuze ugweme ukudideka esimisweni zohambo nezinye izimo, uthi bafuna ukuhlanganisa yonke insimu yabo ngaphansi izoni yesikhathi efanayo, namandla imidondoshiya kuphela ezifana Russia noma e-United States, kufanele wabelane ezweni mayelana nesikhathi. Evamile, imbulunga yonke uhlukaniswe 24 wonke sezigaba zezikhathi. Universal ihlolwa GMT. Le ndawo zero isikhathi (UT0). Konke eNtshonalanga Yurophu, ngaphandle UK, Ireland nasePortugal, uhlala endaweni UT +1. Kulokhu, lo emini beqiniso ibalwa endaweni, esisogwini umngcele iPoland eJalimane. Ngakho, e-Spain ilanga selibantu lapho Ukudayela cishe ihora kosuku.

Daylight saving time

Uma sifeza umsebenzi wokulinga bethu isikhonkwane nekhampasi ku Russian Federation, sizodinga isineke. Kungani? Uke ukhohliwe ukuthi eminyakeni embalwa edlule, NgeSonto lokugcina Mashi, bonke waqhubekela phambili imicibisholo ihora elilodwa? I real isikhathi - ubusika. Futhi ehlobo, ngisho eMoscow iza emini ihora ngosuku. Ngokokuqala ngqá okubizwa ngokuthi "imini ukonga" isikhathi olwaqala ngo-1930 "ukulondoloza amandla" ensimini yethu. Khona-ke, eminyakeni yokwakha kabusha ke sahoxiswa. Khona-ke wangena futhi. Futhi-ke, ekugcineni, odokotela baseRussia baye bafinyelela esiphethweni ongaziwa ukuthi njengoba ukushintshela kabili ngonyaka at isikhathi esisha kubathinta kabi emzimbeni womuntu, kubalulekile ukuba ushiye ehlobo. Kunganjani ebusika, kwesokunxele aphume equation.

Uyini PM futhi AM

Nakuba indoda elula emgwaqweni wayebizwa kubalwa ngaphambi nangemva emini. Yize senze division olungamahora angu-24 ngosuku, abantu abaningi abazibheka ezijikelezayo round uhlukaniswe imikhakha nambili. Futhi ngokuvamile kuboniswa ihora, elibonisa inaliti iDemo. Ngesikhathi esifanayo ukungezwa iwashi. Njengoba kuvela, "Ngehora leshumi ube usubuyile ezimbili", "izinsuku ezintathu", "Ngehora leshumi ube usubuyile eziyisithupha". Ngo WaseBrithani isikhathi liye ayiswe ibonisa okuhlukile. Okungukuthi, eqondiswa emini. Ngisho wabingelela ngakho: «Sawubona!» - kusho "poslepoludnya ezinhle kuwe." vremyaischislenie okunjalo wasinda futhi manje, ngaphezu kwalokho, liye isicelo emazweni owayedlalela amakoloni British. Kulapho ungathola izinkulumo ezinjengokuthi eziyinqaba njengoba 8 AM kanye 3 PM. Njengoba yahunyushelwa olimini isiRashiya, kusho eziyisishiyagalombili ekuseni lesithathu ntambama. Yayisekelwe Kuyinkolelo-ze ukuhlukana isikhathi kwaze kwaba semini, bese zivela Latin ephakathi. Lokhu kufakazelwa esithi uqobo. Ngakho, AM kuyinto segama ante meridiem (ngaphambi emini). A PM, ngokulandelana, we Isinqumo isikhawu esiphakathi 12 ezimpondweni ntambama phakathi kwamabili.
