Zuva rezuva (kana sol) paMars rakareba zvishoma kupfuura zuva repasi: maawa makumi maviri nemana, maminetsi makumi matatu nemapfumbamwe, uye masekondi makumi matatu nemashanu nemashanu. Gore reMars rakaenzana nemakore mazana masere nemakumi masere nemapfumbamwe epasi, kana gore rimwe, mazuva mazana matatu nemakumi matatu nemashanu nemaawa makumi masere nemaviri. Iyo axial tilt yeMars iri 25.19 zvine chekuita neayo orbital ndege, iyo yakafanana ne axial tilt yePasi. Semhedzisiro, Mars ine mwaka yakafanana nePasi, kunyangwe paMars ivo vangangoita zvakapetwa kaviri nekuti nguva yayo yekutenderera yakarebesa. Muzuva ranhasi, iyo epoch yechitenderedzo chechamhembe kweMars iri padyo padyo neDeneb nyeredzi.Mars ine yakanyanya kunzwika eccentric orbital kutenderera kweanenge 0.09; yevamwe vanomwe mapuraneti epasi: maawa makumi maviri nemana, maminetsi makumi matatu nemapfumbamwe nemashanu nemashanu, uye masekondi makumi mana nemana nemashanu.
