Ngisho okhokho bethu, ababekude nesayensi, babazi ngama-solstices amabili nama-equinox amabili. Kepha uyini umongo walezi zigaba "zesikhashana" kumjikelezo waminyaka yonke kwacaca kuphela ngokuthuthuka kwesayensi yezinkanyezi. Okulandelayo, sizobhekisisa ukuthi lemiqondo emibili isho ukuthini.
ISolstice - kuyini?
Ngokombono womndeni, i-solstice yasebusika isho usuku olufushane kakhulu lwasebusika lonyaka. Ngemuva kwalokho, izinto zisondela entwasahlobo futhi nenani lamahora emini landa kancane kancane.

Kumele kuqashelwe ukuthi kungalezi zikhathi lapho amanye amaholide obuqaba ewa, futhi ikhalenda yezolimo yakhiwe ngokunembile ngesisekelo salezi zinqubo zemvelo.
Ngokuqondene namaholide, sisabungaza amanye awo:
- usuku lwasebusika olufushane kunazo zonke nguKhisimusi wabantu benkolo yamaKatolika, uKolyada;
- isikhathi se-equinox yomlomo - isonto likaMaslenitsa;
