Halving day 2012 (November 28, 2012) was the day of the first subsidy halving, which occurred when block 210000 was solved. Until block 420000, the block reward would be 25 BTC instead of the original 50 BTC.
At the moment before the halving, there were 10,500,000 BTC in existence, 50% of the target cap.
