Katika Dunia, majira yanapatikana kutokana na sayari hiyo kuligunzuka Jua na kuwa na mhimili usio wima. Kwa kawaida yanahesabika majira manne: majira ya kuchipua, majira ya joto, majira ya kupuputika majani na majira ya baridi. Katika Afrika Mashariki mara nyingi yanajitokeza zaidi majira ya mvua na kiangazi.
