From forty days to 1000 Years.
Jesus spent forty days here on earth after He arose from the dead, He appeared to His Disciples and to reassure the many secret believers. He also reinstated Peter and appeared at one time to over five-hundred people. Then He had to return to Heaven to allow the Holy Spirit to be given to all believers.
These avents are all miracles in their own right, they are beyond the comprehension of the human mind and that is why believers have the Holy Spirit to help.
Jesus promised he would return and He will at the Fathers will, when He does he will rule on the earth for 1000 years and protect and defend the Kingdom of Israel.
