Tower of London question

I purchased tickets for the Tower of London for Sept 1 but because of another tour I would like to go on August 31 instead. The website says the tickets are good within 7 days of the date selected, but my printed ticket has no notation of that. Will I be able to use my tickets I purchased or should I buy another ticket for the august 31 date?

Thank you for answering what is probably a very obvious question....I just want expert confirmation!

I believe they are valid for 7 days after the ticket date, not 7 days either side.

However I would call/email them to check your options.

You can cancel the Sept 1 for full refund and buy the Aug 31
