Is there a way I can find out when my credit cards were opened and/or closed? I have a spreadsheet where I track this information, but where I have to cut it close (a bonus expiring within a few days, etc.) it would be nice if I can somehow confirm what the BANK reflects as the open/close dates of accounts. I would hate to be denied a bonus because my chart (where I list the day I applied for the card) is off by a day or two for some reason from the bank's. I thought about looking on my credit report but I think this only shows openings, not closings, and wouldn't there be a slight lag between the date of application and it showing up on the credit report?

Thanks in advance.
