user1409: The first Halving Day was November 28, 2012, when block 210000 was generated.
How many more Halving Days will there be?

user5406: The block subsidy will be reduced 33 times, 32 of them halving the block reward, and the last ("33rd halving") reducing it from 1 satoshi per block to zero satoshis per block.
You can find a table here (Google doc) that shows some metrics of the Bitcoin reward schedule including e.g. the number of halvings, their first blocks, and how much supply is left to be mined after each epoch.

user403: There will be 32 more if the precision doesn't increase. If Bitcoin lasts this long (very unlikely), precision probably will be increased.
