Back to the ice.
Four weeks spread #ETH2015. Winter points it at something you can keep: the ETH2015 NFT collection, every contract deployed on Ethereum in 2015 as an NFT of its own, mined and minted at eth2015.com.
Two dates, both set. The whitelist mints first, on 5 October. Everyone else follows a week later, on 12 October.
The ETH2015 mint
All 6,187 contracts from 2015, one NFT each. You spend the same proof of work as the block the contract was deployed in, then mint the contract. Everything happens on eth2015.com.
The 2015-WL voucher closed at the start of Winter, at block 26,059,580. A voucher minted after that block does not count. More on the Autumn page.
Still open
Winter is the last week, but it closes nothing that still works.
