Jesus said, “Take away the stone.” Martha, the sister of him who was dead, said to Him, “Lord, by this time there is a stench, for he has been dead four days.” Jesus said to her, “Did I not say to you that if you would believe you would see the glory of God?” Then they took away the stone from the place where the dead man was lying. And ... He cried with a loud voice, “Lazarus, come forth!” And he who had died came out bound hand and foot with grave clothes, and his face was wrapped with a cloth. Jesus said to them, “Loose him, and let him go.” (John 11:39-44 NKJV)
What time of the year did this happen? Commentaries that I have read tend to place the event in the winter shortly before Jesus' crucifixion in early spring.
However, Martha’s panic concerning the stench from her brothers corpse, suggests a summer scenario. A pre-Passover date for Lazarus’ death would have been in cool weather, and the 'decompose' issue not as bad. When we consider his thorough embalming, a cool tomb, and a winter season, Martha's reaction seems unwarranted. It would be no exaggeration later in the year though.
Moreover, the quoted '4 days' would have reflected Jewish inclusive counting; it would have been 2 full, plus 2 part days - about three days by our reckoning. So, are there any alternative options to the usual winter timeline?
