What happened on the 24th?
Reward halving happened on 2014-12-06.
Current reward in range 1k6.25k MEOW. So, average reward per block is 3.625k MEOW.
Daily emission amount is 24*60*3.6k = 5.2M MEOW
So, inflation rate is 5.2M*365/23'385M*100% = 1.9B/23.4B*100% = 8% per annum (theoreticaly)
Really number of blocks generated per day is less than 1440 because of hashrate instability.

Correction factor is 870/1440 = 0.6
So, real inflation rate now is 8%*0.6 =
4.8% per annum
