Kwikhalenda yenyanga, inyanga ethe tyaba yinyanga eyongezelelweyo eyongezwa kwikhalenda ukuze ikhalenda yenyanga ihambelane nonyaka welanga. Ikhalenda yenyanga isekelwe kwimijikelo yenyanga, emalunga neentsuku ezingama-29.5, ngoko ke unyaka wenyanga ubude bumalunga neentsuku ezingama-354. Oku kumfutshane kunonyaka welanga, omalunga neentsuku ezingama-365.24.
Ukuze ikhalenda yenyanga ihambelane nonyaka welanga, kongezwa inyanga eyongezelelweyo kwikhalenda yenyanga phantse rhoqo emva kweminyaka emithathu. Inyanga ethe tyaba ifakwa emva kwenyanga ethile kwikhalenda yenyanga, kwaye inikwa igama elifanayo naleyo nyanga, kodwa kongezwa igama elithi “thaba”. Umzekelo, inyanga ethe tyaba eyongezwa emva kwenyanga yesithathu ibizwa ngokuba “yinyanga yesithathu ethe tyaba” okanye “inyanga yesithathu ethe tyaba”. Inyanga ethe tyaba ikwabalwa njengenyanga eqhelekileyo, kwaye zonke iiholide kunye nemibhiyozo eyenzeka ngaloo nyanga zibhiyozelwa njengesiqhelo.
Imfuneko yenyanga eqamkileyo kwikhalenda yenyanga ivela kuba imijikelo yenyanga kunye nemijikelo yelanga ayihambelani ngokuchanekileyo. Ukongeza inyanga eqamkileyo kuqinisekisa ukuba ikhalenda yenyanga ihlala ihambelana namaxesha onyaka, kunye nekhalenda yelanga.
