Iqukethe izikhangiso

Mayelana nalolu hlelo lokusebenza

I-formula
Ifomula:

(Inyanga Unyaka Ikhodi + Ikhodi + Century Ikhodi + Usuku Inombolo - Leap Year Ikhodi) mod 7

Nakhu INDLELA ESEBENZA
Ngizobuya qhaqha isibonelo nge usuku, 14 Mashi 1897 - lokuzalwa Einstein.

Umnyaka Ikhodi
Ukuze abale Ikhodi Year, sebenzisa lokhu ifomula:

(YY + (YY div 4)) mod 7

YY iyona amadijithi amabili ngonyaka. Ukuze onyakeni 1897, kungcono 97.

Okokuqala, uhlukanise YY by 4 bese ulahla okusele: 97 div 4 = 24.

Bese wengeza 24 emuva ku inombolo YY, okuyinto 97 kuleli cala, okuholela 121.

Isinyathelo esilandelayo: 121 Mod 7.

"Mod" kusho ukwehlukana inombolo bese ugcine kuphela okusele. Ukuze 121 Mod 7, qala ekususeni ngasikhombisa:

10 x 7 70, enishiyela nge 51, ngoba 121 - 70 = 51.
7 x 7 = 49 no 51 - 49 = 2.
Sisuse zonke ngasikhombisa kusuka 121 kuze thina isala esele 2. Lokho Ikhodi Umnyaka 1897.

Ungase usebenzise isithombe inombolo ukuma sengathi dada ukubamba ukuze ikhumbule ngenkathi ukubala izinto ngaphansi.

I Inyanga Ikhodi
Lokhu kulula - nje ngekhanda inombolo 033614625035:

Januwari = 0
Februwari = 3
Mashi = 3
Apreli = 6
May = 1
Juni = 4
Julayi = 6
Agasti = 2
Septhemba = 5
Okthoba = 0
Novemba = 3
Disemba = 5
Manje unayo Ikhodi Inyanga. Ukuze Einsteins lokuzalwa ngoMashi, kuba 3.



Izinsuku Gregorian

Ukuze Ikhalenda likaGregory, khumbula inombolo 4206420:

1700s = 4
1800s = 2
1900s = 0
Kowezi-2000 = 6
2100s = 4
2200s = 2
2300s = 0
Uma kuphela ukwenza lesi senzo ikhalenda ne zokuzalwa zabangani, ungase mhlawumbe ukushiya lesi sinyathelo ngaphandle, ngoba izinsuku iwe 1900s ukuthi uthole Ikhodi Century ka-zero futhi musa umphumela ukubala.

Izinsuku Julian
Uma ufuna ngosuku Julian, ifomula ukuthatha inani ekhulwini nokukhupha ke kusukela 18 bese MOD 7.

Isibonelo 1: uma unyaka 852 CE, thatha isibalo leminyaka, 8, bese ukhupha ke kusukela 18, kusale 10. Khona-ke, 10 mod 7 = 3.

Isibonelo 2: uma unyaka 1625 CE, thatha isibalo ekhulwini, 16, bese ukhupha ke kusukela 18, kusale 2. 2 mod 7 = 2, ngakho kulesi simo Ikhodi Century kuyinto 2.

Ukuze Einsteins lokuzalwa ngo-1897, i-Code Century kuyinto 2, ngoba usuku Gregorian, futhi ishadi elingenhla libonisa ukuthi sihlehlela e 1800s uthole ukuhlela 2.

Leap Ikhodi Year
Enye into acabangele ingabe wena obhekana nakho ngonyaka eqa. HLELA: Uma usuku endaweni Januwari noma Februwari ngonyaka eqa, kufanele sisuse umuvo kusukela Imininingwane yakho ngaphambi isinyathelo sokugcina.

Gregorian Calender
Uma ungakwazi ukuhlukanisa unyaka Gregorian ngu 4, kungcono ngonyaka eqa, ngaphandle uma sihlukaniswe ngu-100 Kodwa ngonyaka eqa uma sihlukaniswe ngu-400.

1992 is unyaka eqa ngoba ungakwazi ulwahlukanise ngabantu abane.
1900 akuyona ngonyaka eqa ngoba ungakwazi ulwahlukanise ngu-100.
2000 is unyaka eqa ngoba ungakwazi ulwahlukanise ngu-400.

Julian Ikhalenda
Uma ungakwazi ukuhlukanisa unyaka Julian ngu 4, kungcono ngonyaka eqa.

lokuzalwa Einstein kwaba ngo-1897 lapho kwakungelona ngonyaka eqa (0), ngakho-ke akuphazamisi umphumela.

Ibala Day
Emuva ifomula yasekuqaleni:

(Inyanga Unyaka Ikhodi + Ikhodi + Century Ikhodi + Usuku Inombolo - Leap Year Ikhodi) mod 7

Ukuze 14 Mashi 1897, nawa imiphumela:

Ikhodi Unyaka: 2
Ikhodi Inyanga: 3
Ikhodi Century: 2
Inombolo Usuku: 14 (14 lwenyanga)
Leap Ikhodi Unyaka: 0
Ngakho:

(2 + 3 + 2 + 14) mod 7 = 21 mod 7 = 0

Matanisa inombolo okuholela Ohlwini olungezansi, futhi uzoba usuku lweviki:

0 = ngeSonto
1 = ngoMsombuluko
2 = ngoLwesibili
3 = ngoLwesithathu
4 = ngoLwesine
5 = ngoLwesihlanu
6 = ngoMgqibelo
Einstein wazalwa ngeSonto.

Izibonelo angeziwe
Nazi izibonelo ezintathu ngaphezulu kusuka eminyaka ehlukene:

The Moon Landing
Abantu setha unyawo inyanga: 20 Julayi 1969:

Thatha '69 futhi wehlukanisa 4, ukulahla isalela. Lokho kushiya 17. Engeza 69 17 ukuze uthole 86. Khona-ke, 86 mod 7 = 2. Ikhodi Unyaka 2.
I Inyanga Ikhodi July 6.
Ekhulwini Ikhodi 1900s zero.
Inombolo Usuku 20, ngoba 20 Julayi.
1969 kwakungelona ngonyaka eqa ngoba ayikwazi ehlukaniswa 4.
2 + 6 + 0 + 20 = 28
28 mod 7 = 0
20 Julayi 1969 kwaba ngeSonto.
