以具体的日期表述外，还可以约定以某个事件的发生或不发生作为其生效起点，相当于附条件，只有在所附条件成立时合同才生效，比如在一个中外合资合同中：TheAGREEMENTshalltakeaffectupontheapprovalfromtheMinistryofCommerceofthePeople’sRepublicofChina.本协议自中国商务部批准之日起生效。再如：TheAGREEMENTshallbedeemedtohavecomeintoeffectonthedatewhenItalyhaspassedtheLAWtocooperatewithChinaconcerningSERVICES.当意大利方面依据法律批准了与中国的该服务时，本协议视为生效。如合同自签字之日起经过六个月仍不能生效，则双方有权取消本合同。IftheContractcannotcomeintoforcewithin6(six)monthsafterthedateofsigningtheContract,bothpartiesshallhavetherighttocanceltheContract.ThisAGREEMENTshalltakeeffectfromtheEFFECTIVEDATEprovidedthatiftheEEFFECITVEDATEhasnotoccurredby30November2000,thisAGREEMENTshall(unlessthePARTIESagreeotherwise)automaticallyterminateandeachofthePARTIESheretoshallbereleasedfromanyfurtherobligationshereunder。本协议生效日期为2000年11月30日，但如果届时未能生效，除非各方另有约定，本协议自动解除，各方互不承担责任。采购协议的生效视另一个事件是否发生。为避免合同签订后其效力处于不确定的状态拖得太长，可在合同中约定，在某种条件下，合同永不生效，比如：ThisAGREEMENTshallnevertakeeffectprovidedthatPARTYBcannotgettheapprovalfromthecompetentauthoritywithinthirty(30)daysafterthesignatureofthisAGREEMENT.合同签订后30日内乙方没有获得自己政府批准，则本协议自动解除。例：本合同由双方代表于1999年12月9日签订。合同签订后，由各方分别向本国政府当局申请批准，以最后一方的批准日期为本合同的生效日期，双方应力争在60天内获得批准，用电传通知对方，并用信件确认。若本合同自签字之日起，6个月仍不能生效，双方有权解除本合同。ThiscontractissignedbytheauthorizedrepresentativesofbothpartiesonDec.9,1999.Aftersigningthecontract,bothpartiesshallapplytotheirrespectiveGovernmentAuthoritiesforratification.Thedateofratificationlastobtainedshallbetakenast
