Salom, shuni payqadimki, har yili karnavalning sanasi o'zgarib turadi.<|eot_id|><|start_header_id|>assistant<|end_header_id|>

Ha, karnavallar sanasi har yili o'zgarishi mumkin, chunki ular oy taqvimi va Pasha sanasiga bog'liq. Karnavallar sanasi Pasha sanasiga qarab belgilanadi, bu esa katolik cherkovida belgilanadi. Pasha sanasi Nikeya kengashi qoidalariga muvofiq belgilanadi, bu esa Pasha bahor tengligidan (shimoliy yarim sharda) yoki kuz tengligidan (janub yarim sharda) keyingi to'lin oydan keyingi birinchi yakshanba kuni bo'lishi kerakligini belgilaydi.<|eot_id|>
