This means, that when block 1.400.000 is minted, the changes to the block reward will be active. Block 1.400.001 will then be the first block with the new block rewards. This is in approximately 50.000 minutes from now (time of publication). And is expected to be around July the 1st this year (2021).
Can't believe Rijk is going ahead with the change and only 21 days away. I will believe it when I see it.
Do you guys even know how decentralized software works? It's not a switch that Rijk pushed on block 1,400,000 and then the rewards are reduced. No, that change has long been incorporated into the current software (version 2.3.12) of the wallets. The wallet software sees that we have arrived at the conscious block and then the new rewards become active. So no one can change this anymore except by not updating, but then you are on the wrong chain after block 1,400,000.
