title_body: Why do Daedalus Rewards Report Epoch End Dates differ from other sources?
upvoted_answer: Rewards for a given epoch X are paid out at the end of the next epoch, X+1. This is because the calculation of which stake keys get rewards is done during epoch X+1.
  Applying this to your example, the order of events would be:
  
  April 25th - epoch 261 ends
  April 30th - epoch 262 ends - rewards from epoch 261 are paid
  April 30th - epoch 263 starts - CSV report and adastat.net list current date and epoch.
  
  The terminology of rewards being &quot;paid&quot; is somewhat misleading, since there are no transactions that correspond to the rewards entering your wallet. Instead, the amount of rewards for all stake keys is stored separately in the ledger, and that table is updated on epoch boundaries. Your private stake key then allows you to withdraw/send the rewards along with regular transactions.
