Last day of every year, my wife and I sit down and update logins/ passwords, and /or new address, phone numbers, email,etc. for critical accounts. We have been doing so for past three years now.
Between the 1st and 7th of January each year (and again on 1st and 7th of July), I change passwords for most active services. I also purge out half baked/ inactive services.
Since this morning, I have cancelled 10 services, and slayed some Ghosts of the past (Attaching an image below for example) This was a "Lifetime" storage deal w/ 1.2 TB cloud storage, the service is closing on Jan 31st. No need to wait that long IMO.

Technically, our New Year begins sometimes in end of March/ early April, but we follow the Gregorian calendar for the above.
