Yini ukubaluleka konyaka we-leap ekhalendeni?

Yini ukubaluleka konyaka we-leap ekhalendeni?

Umhla zingama-29 kuNhlolanja uyivelakancane, njengoba kuwukuphela kosuku olungenzeki minyaka yonke, kodwa lutholwa abantu kanye njalo eminyakeni emine.Labo abazalwa ngalolu suku bathathwa njengabaneshwa kakhulu phakathi kwabantu ngoba usuku lwabo lokuzalwa aluveli minyaka yonke. kodwa kanye njalo eminyakeni emine.

Iminyaka eyiLeap iminyaka equkethe izinsuku zekhalenda ezingama-366 esikhundleni sezinsuku zekhalenda ezingama-365, futhi zenzeka njalo eminyakeni emine ekhalendeni likaGregory, okuyikhalenda elisetshenziswa manje iningi lamazwe emhlabeni. Usuku olwengeziwe, olwaziwa ngokuthi usuku lwe-leap, lungoFebhuwari 29, olungekho eminyakeni engeyona eye-leap.

Ngamanye amazwi, unyaka ngamunye ohlukaniswa ngezine unyaka we-leap, njengo-2020 no-2024, ngaphandle kweminyaka eyikhulu noma iminyaka ephela ngenombolo 00, njengonyaka we-1900.

Iwebhusayithi ethi "Live Science", egxile ezindabeni zesayensi, ishicilele umbiko onemininingwane, i-Al Arabiya Net ewubuke, echaza izizathu nokuthi "unyaka we-leap" uvele kanjani, nomlando wawo emhlabeni.

Lo mbiko uphawula ukuthi amanye amakhalenda angewona awaseNtshonalanga, okuhlanganisa ikhalenda lamaSulumane, ikhalenda lesiHeberu, ikhalenda lamaShayina, kanye nekhalenda laseTopiya, nawo anezinguqulo zeminyaka ye-leap, kodwa le minyaka awafiki wonke njalo ngemva kweminyaka emine futhi ngokuvamile ivela eminyakeni. ehlukile kulawo asekhalendeni likaGregory. Amanye amakhalenda aqukethe nezinsuku eziningi ze-leap noma ngisho nezinyanga ezifushanisiwe ze-leap.

Ngokungeziwe eminyakeni ye-leap nezinsuku ze-leap, ikhalenda (laseNtshonalanga) likaGregory liqukethe inani elincane lamasekhondi e-leap, angezwe ngezikhathi ezithile eminyakeni ethile, muva nje ngo-2012, 2015 kanye no-2016. Kodwa-ke, i-International Bureau of Weights and Measures (IBWM), okuyinhlangano ebhekele ukugcina isikhathi emhlabeni wonke, izosusa imizuzwana emincane kusukela ngo-2035 kuya phambili.

Kungani sidinga iminyaka ye-leap?

Umbiko we-Live Science uthi iminyaka ye-leap ibaluleke kakhulu, futhi ngaphandle kwayo, iminyaka yethu izobukeka ihluke ngokuphelele ekugcineni. Iminyaka eyiLeap ikhona ngoba unyaka owodwa ekhalendeni likaGregory mfishane kancane kunonyaka welanga noma wezindawo ezishisayo, okuyinani lesikhathi esithatha umhlaba ukuzungeza ilanga ngokuphelele ngesikhathi esisodwa. Unyaka wekhalenda unezinsuku ezingama-365 ubude, kepha unyaka welanga cishe unezinsuku ezingama-365.24, noma izinsuku ezingama-365, amahora ama-5, imizuzu engama-48 nemizuzwana engama-56.

Uma singawunaki lo mehluko, njalo ngonyaka odlulayo sizorekhoda igebe phakathi kokuqala konyaka wekhalenda kanye nonyaka welanga elizokhula ngamahora angu-5, imizuzu engu-48 nemizuzwana engu-56 njalo ngonyaka, futhi lokhu kuzokhula. shintsha izikhathi zonyaka. Isibonelo, uma siyeka ukusebenzisa iminyaka ye-leap, ngemva kweminyaka engaba ngu-700, ihlobo eNyakatho Nenkabazwe lizoqala ngo-December esikhundleni sikaJuni.

Ukwengeza izinsuku ze-leap njalo ngonyaka wesine kuyiqeda kakhulu le nkinga ngoba usuku olwengeziwe lucishe lulingane nomehluko onqwabelana ngalesi sikhathi.

Nokho, uhlelo aluphelele: sizuza cishe imizuzu engama-44 eyengeziwe njalo eminyakeni emine, noma usuku olulodwa njalo eminyakeni eyi-129. Ukuxazulula le nkinga, seqa iminyaka ye-leap njalo ngonyaka wekhulunyaka ngaphandle kwaleyo ehlukaniswa ngama-400, afana no-1600 no-2000. Kodwa nangaleso sikhathi, wawusemncane umehluko phakathi kweminyaka yekhalenda kanye neminyaka ezungeza ilanga, yingakho i-International Bureau of Weights and Measures nayo yazama ukusebenzisa imizuzwana.
Kodwa ngokuvamile, iminyaka ye-leap isho ukuthi ikhalenda likaGregory (laseNtshonalanga) lihlala lihambisana nohambo lwethu lokuzungeza ilanga.

Umlando weminyaka ye-leap

Umqondo weminyaka eyi-leap uhlehlela emuva ku-45 BC, lapho uMbusi wasendulo waseRoma uJulius Caesar esungula ikhalenda likaJulius, elalinezinsuku ezingama-365 ezihlukaniswe izinyanga eziyi-12 esisazisebenzisa ekhalendeni likaGregory.
Ikhalenda likaJulius lalihlanganisa iminyaka ye-leap njalo eminyakeni emine ngaphandle kokukhetha, futhi lalivunyelaniswa nezinkathi zonyaka ngenxa yokuthi "Unyaka Wokugcina Wesiphithiphithi" ngo-46 B.C., owawuhlanganisa izinyanga ezingu-15 nengqikithi yezinsuku ezingu-445, ngokusho kweNyuvesi yaseHouston.

Emakhulwini amaningi eminyaka, ikhalenda likaJulius lalibonakala lisebenza kahle, kodwa phakathi nekhulu le-10, izazi zezinkanyezi zaqaphela ukuthi izinkathi zonyaka zaziqala cishe izinsuku eziyi-XNUMX ngaphambi kwalokho okwakulindelekile lapho amaholide abalulekile, njengePhasika, engasahambisani nezenzakalo ezithile, njengezinsuku zangasese. i-equinox.

Ukuze kulungiswe le nkinga, uPapa Gregory XIII wethula ikhalenda likaGregory ngo-1582, elifana nelekhalenda likaJulius kodwa alibandakanyi iminyaka ye-leap iminyaka eyikhulu.

Emakhulwini amaningi eminyaka, ikhalenda likaGregory lalisetshenziswa amazwe amaKatolika kuphela, njenge-Italy neSpain, kodwa ekugcineni lamukelwa namazwe obuProthestani, njengeGreat Britain ngo-1752, lapho iminyaka yalo iqala ukuphambuka ngokuphawulekayo emazweni amaKatolika.

Ngenxa yomehluko phakathi kwamakhalenda, amazwe kamuva ashintshela ekhalendeni likaGregory aphoqeleka ukuba eqe izinsuku ukuze ahambisane nomhlaba wonke. Ngokwesibonelo, lapho iBrithani ishintsha amakhalenda ngo-1752, u-September 2 walandelwa u-September 14, ngokweRoyal Greenwich Museum.

Umbiko we-Live Science uphetha ngokuthi abantu bazophoqeleka esikhathini esithile esikhathini esizayo esikude ukuba bahlaziye kabusha ikhalenda likaGregory ngoba alihambisani neminyaka yelanga, kodwa kuzothatha izinkulungwane zeminyaka ukuthi lokhu kwenzeke.
