Isifinyezo se-Nyanga para Septhemba
Ku Septhemba 2026, kunezigaba ezinkulu zenyanga 4: Ilanga Elingako Kwesibili (Sep 4, 2026), Ilanga Elitsha (Sep 11, 2026), Ilanga Elinye Elingako (Sep 18, 2026) & Ilanga Elikhulu (Sep 26, 2026).
Imibuzo Evamile ye-Ikhleandule Langa
Zibalwa njani ikhwele langa?
Ikhleandule isebenzisa algorithm ye-Jean Meeus ye-astronomy (Astronomical Algorithms, Chapter 49) enama-25 amathemu okulungisa. Ibala isikhathi se-ilanga elintsha, eliphakama, nelinquqwabe ngencinane ezingakusingizayo isikhathi se-USNO ngo-abasekhethi amabili.
Uyini usuku lwelanga?
Usuku lwelanga lubhekisa usuku naphakathi nenziwa yenyanga (umjikelezo kusukela kumkholi omutsha kuya komkholi omutsha olandelayo), okuthatha amasekhethi angaphansi kwangakoka-29.53 usuku. Usuku 0 kuqalisha kumkholi omutsha, futhi usuku ~14.8 okuyisikhatshelo somkholi ophakamisile.
Ilanga elihlangothi elikuza?
Isikhathi esengemuva somkholi ophakamisile kubonakala ekhalendeni ekhona. Ikhwele elimahle (umkholi omutsha, ingingo yokuqala, umkholi ophakamisile, ingingo yokugcina) ibonakaliswe nesikhathi okuliqiniso se-UTC.
Uku khanya ngepeesenti kusho ukuthini?
Ukukhanya kukhombisa ingxenye yomkholi eyawulayo elanga. 0% kusho umkholi omutsha (umnyama okupela), 50% kusho ingingo, futhi 100% kusho umkholi ophakamisile.
Izincwadi Ezihlanganisiwe
Ikhwele Langa Alaye: Ihlahlumaniso Elingazidlalela — Yonke into oyisidingo nayo ukuze uzazi ngekhwele elanga engathathu — kusukela kumkholi omntsha kuya omkholi ophakamisile futhi emuva. Sayensi yesigaba solanga 29.53-usuku se-synodic alaye.
Iyini i-Coordinated Lunar Time (LTC)? — I-hlahlumaniso elingazidlalela mayelana no-NASA's umkela ka-Coordinated Lunar Time — umkela wesikhathi omtsha weLanga nokuba yini okuthiwa
