/sci/, I know it's been 3 years since I've been here but please help an r9k brainlet out with credit card closing dates so I can make sure to pay everything off before the closing date and not use my card for anything to avoid pending purchases prior to the balance reporting period, because this is all just stupid and confusing to me. There's no option have auto-pay set to automatically pay off my statement balance in full before the closing date, just every 30 days or whenever the statement balance is due instead of whenever the closing / reporting period ends.

I have 3 cards: Capital One, Discover, and Amex

Based off my statements, If the Capital One closing dates are...
Oct. 20 - Nov 21 (33 days in billing cycle)
Nov 22 - Dec 22 (31 days in billing cycle)
Dec 23 - Jan 22 (31 days in billing cycle)
Jan 23 - Feb 19 (28 days in billing cycle)
Feb 20 - Mar 22 (31 days in billing cycle)
Mar 23 - Apr 21 (30 days in billing cycle)

My Discover statements show...
Jan 22 - Feb 10
Feb 11 - Mar 10
Mar 11 - Apr 10

And Amex...
Feb 23 - Mar 25
Mar 26 - Apr 23
Apr 24 - (upcoming) May 25

What will my closing dates be with each card for the rest of the year?
