I-Calculator yosuku lweviki
Thola ukuthi yini usuku lweviki lapho umhla udlula khona, kumasuku adlule noma azayo.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
A day of the week calculator tells you which day a given date lands on — Monday through Sunday — for any date, past or future, using the browser’s proleptic Gregorian calendar. Alongside the weekday it reports the day number within the year (1–365 or 366), the ISO-8601 week number, whether the year is a leap year, and how many days remain until the end of the year. It is handy for planning events, checking historical dates, or working out which weekday a birthday or anniversary falls on in a future year.
You simply enter a date (or leave it blank for today) and it maps that date to a definite weekday using the proleptic Gregorian calendar built into every browser — the modern calendar rules projected consistently backward and forward in time. The same lookup yields the day-of-year number, the ISO week the date belongs to, and whether that year carries a 29 February, so a single answer covers several common questions at once.
For example, 4 July 1776 was a Thursday, and 1 January 2000 was a Saturday; enter your own birthdate and you can see which weekday you were born on, then check which weekday it falls on this year. People use it to plan events onto a particular weekday, settle "what day was I born" questions, verify a historical date, or work out that a fixed-date holiday shifts to a new weekday each year.
Imibuzo ebuzwa kaningi
Usuku lweviki luyacaciswa kanjani?
I-calculator isebenzisa ikhalenda le-Gregorian proleptic (ifana nenye eyenziwe kuwo wonke umsakazo), ebonisa imithetho yekhalenda yanamuhla ebuyela emuva neya phambili, ngakho noma yiluphi usuku luzobeka izithombe kusuku lweviki olucacile kusuka ngoMsombuluko kuya kuLwesihlanu.
Yini inani leviki le-ISO?
Nge ISO 8601, amaviki aqala ngoMsombuluko futhi amaviki 1 yiwo amaviki aqukethe uLwesihlanu wesibili weminyaka (olinganayo, amaviki aneJanuwari 4). Lokhu kusho ukuthi amasonto aqala ngoJanuwari noma aphelile ngoDisemba angaba yiwo amaviki 52/53 weminyaka engaphansi.
Ingabe isebenza kumasuku angaphambili kwe-1900 noma asentshonalanga?
Yebo. Ngenxa yokuthi isebenzisa ikhalenda le-Gregorian proleptic iphatha amahora emlando nesikhathi esizayo ngokuqinile, nakuba amahora ehlabathini elidala kakhulu ikhalenda lemlando esetshenziswa ngesikhathi (isibonelo iJulian) ingahluka.
Yini usuku lweviki lapho ngizalwa khona?
Ngeza usuku lokuzalwa lwakho negama le-calculator lemingwane yesonto lapho idlula khona, kanye nenombolo yosuku lweminyaka kanye nokuthi ngabe yiminyaka ehamba phambili — indlela esheshayo yokuxazulula "ngosuku luni lapho ngizalwa khona".
Kungani usuku lokuzalwa ludlula ngosuku oluhlukile lweviki ngonyaka?
Unyaka ojwayelekile usuku 365, okungukwesithupha esingu-52 kanye nosuku olungeziwe olulodwa, ngakho usuku oluqinile luvame ukuqhubeka usuku olulodwa lwesithathu ngonyaka kanye namashumi amabili ngonyaka odlule. Ngeza usuku lweminyaka ehlukene ukuze ubone imodeli.
Yishiye usuku olungenalutho — yini ekwenzekile?
Uma ushiya indawo engenanto i-calculator isebenzisa usuku lwamanje, ngakho iphinda i-"what day is it today" check kanye nosuku lweminyaka nenombolo yeviki.
Ingaba itshela ukuthi ngabe unyaka unyaka ohamba phambili?
Yebo. Ikhombisa ukuthi ngabe unyaka wosuku yiminyaka ehamba phambili (izinsuku ezingama-366) noma unyaka ojwayelekile (izinsuku ezingama-365), okusho ukuthi kungani usuku lweminyaka oluphelele lungafinyelela ku-366.
API — sebenzisa le calculator kusuka kukhodi
Nquma le calculator njenge JSON evulekile yendawo yokuqeda - akukho isithonjana esidingekayo. Thumela amaxabiso endawo ngezansi njengezilungiselelo zombuzo noma i-JSON.
