To avoid such a problem:

* some registries allow for multi-year registration,
* some registrars allow for multi-year registration, and/or automatic
  renewal, so you no longer have to think of it,
* automatic entries in your agenda software is nice, too :-)
* automatic monitoring of expiration (through whois or, better, RDAP,
  later is an example of a Nagios/Icinga/whatever plugin using RDAP).

% /usr/local/lib/nagios/plugins/check_expire -H 2dpnr.org
2dpnr.org OK: expires in 497 days, 13:36:22.602780.
