Charles Ellicott Commentary Ezekiel 29:1

"In the tenth year, in the tenth [month], in the twelfth [day] of the month, the word of Jehovah came unto me, saying," — Ezekiel 29:1 (ASV)

In the tenth year, in the tenth month. — This was exactly a year and two days after the siege of Jerusalem by Nebuchadnezzar (Ezekiel 24:1–2; 2 Kings 25:1), and about six months before its fall, or seven before its destruction (2 Kings 25:3–8).

It must have been, therefore, after the time when the siege was temporarily raised by the approach of the Egyptians under Pharaoh-Hophra (Jeremiah 37:5; Jeremiah 37:11), and when Jeremiah prophesied the failure of that attempt (Jeremiah 37:6–10). And it probably was just when the news of that relief reached Chaldea and gave fresh hope to the exiles of the deliverance of Jerusalem.
