How do I download the blockchain from a specific height (409668) I'd like to download the blockchain from height 409668 (first block on May 1st). I need data on time it was mined, and the amount of transactions it included. 

If I don't need to download the blockchain to get this data, that would be 10x better. Where can I get a CSV of this? Otherwise, where can I download the blockchain and get this data from?
This should make it for you: https://blockchair.com/bitcoin/block/409668

Hope it helps.
