Question: Read this and answer the question

While Goring was optimistic the Luftwaffe could prevail, Hitler was not. On 17 September he postponed Operation Sea Lion (as it turned out, indefinitely) rather than gamble Germany's newly gained military prestige on a risky cross-Channel operation, particularly in the face of a sceptical Joseph Stalin in the Soviet Union. In the last days of the battle, the bombers became lures in an attempt to draw the RAF into combat with German fighters. But their operations were to no avail; the worsening weather and unsustainable attrition in daylight gave the OKL an excuse to switch to night attacks on 7 October.

When did the OKL switch to night raids?
Answer: 7 October
