From the flow of scriptures in book of John the timing was most likely Pentecost.  The woman was most likely an outcast for appearing at noon to draw water alone. I see the woman as being the church for in this world being a christian is being an outcast. When Jesus and the woman had a discussion over water and the Lord said she should have asked for Living Water which is the Holy Spirit.  The two days represents the two thousand years he would spent with both jew and gentile (Samaritans)  ( which happened at Pentecost). 

Summing things up here I see a revival coming at Pentecost. When Jesus said--"Do you not say four months till the harvest?" Four months from Pentecost would take us to the Feast of Tabernacles. The harvest would have been mostly over at Tabernacles except for the olives. As God gave the ancient world 120 years to acknowledge Him, Jesus confirmed saying 120 days till the Tribulation.

120 days of Revival starting May 23th. The church and jews count the days to Pentecost differently, this year I believe the church is right. Jews count 50 days from the day after Passover and the church counts 50 days after the Passover Sabbath
