I think the actual deadline to place the order was sometime on Thursday.Didn't work for me. I entered an order at 2:20AM EST Fri Dec 29 and the confirmation lists the purchase date as 1-2-2024
You can schedule the purchase in advance, and I've successfully bought I Bonds for the last business day of the month in this manner.
