The first Halving Day was November 28, 2012, when block 210000 was generated.

How many more Halving Days will there be?

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

  • Why should the precision be increased? Many would argue that instead, we will see micropayments move off the blockchain and possibly bitcoin alltogether...

    @pyramids If the value becomes really immense, it may become convenient to increase the precision. And scalability might be significantly improved after many years, possibly allowing microtransactions.

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.
