Remembering the creating date is now important as the support told me they can help me and will send me my old emailadress
if i prove that the wallet id is by me by naming the date or the wallet creating date.
So thats why I need to find a way how I can find out the creation date of the bitcoin adress. I think i created the bitcoin adress the same date as i created the wallet ID on blockchain
It's not possible to find the exact date of the Bitcoin address was generated. This is block explorers only read other information like the transaction timestamps, when the address first received and last received the transaction etc. In this case, at least try to remember if you generated the address the exact day you sent Bitcoins to it. The transaction details could help determine the address generation date.
