Paul writes 2 Corinthians from Macedonia
2 Corinthians 2:12–13; 7:5–7; 11:23–29
Relieved by Titus's report that the Corinthians had repented, Paul wrote his most personal letter, defending his ministry against false apostles and describing both his sufferings and the comfort of God.
Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new.
2 Corinthians 5:17 (World English Bible)
Paul lists what he had endured: beatings, a stoning, three shipwrecks, dangers on every side, and his daily concern for all the churches (2 Corinthians 11:23–28). He wrote of God's power made perfect in weakness (2 Corinthians 12:9).

About AD 55–56, from Macedonia. The date is an estimate; Scripture doesn't say when the book was written.
