Jesus ascended to heaven 40 days after His resurrection. This is based on multiple biblical accounts, particularly in the books of Luke and Acts, which state that Jesus appeared to His disciples and taught them about the kingdom of God for 40 days after rising from the dead before ascending bodily into heaven (Acts 1:3; Luke 24:50-51)

. This 40-day period is commemorated in Christian tradition as the time between Easter (Jesus' resurrection) and Ascension Day, which is celebrated on the 40th day after Easter Sunday. The ascension marked the end of Jesus' earthly ministry and His return to the Father, signifying His exaltation and the beginning of His heavenly priesthood and intercession for believers (Mark 16:19; Luke 24:50-52; Acts 1:9-11)

. In summary:

• Jesus rose from the dead on Easter Sunday.
• He appeared to His followers over a period of 40 days.
• On the 40th day after His resurrection, He ascended to heaven in their presence.
