By default It is 30 days and you can double check if the certificate was renewed by the certbot with openssl:

openssl x509 -in /etc/letsencrypt/live/devuan.org/fullchain.crt -text -noout

(Amend the path accordingly)

If the certificate was renewed, at 99% it's nginx which must be restarted (a reload is not enough).

I hope this helps,
Alberto

FYI, from D1G irc logs:

2017-07-05 08:58:49 rrq: re cert: the standard set up runs "certbot
renew" every 12 hours (midday + midnight), which
2017-07-05 08:59:14 rrq: supposedly renews the cert if near expiry.
2017-07-05 08:59:26 rrq: I'm trying to find out what "near" means.
2017-07-05 08:59:43 rrq: logically it should be >12h
2017-07-05 09:00:46 rrq: but there's been some serious python vomit:
7425 lines to do its thing :-(
2017-07-05 09:09:30 rrq: hmm default renewal supposedly is 30 days (or
less) before expiry
2017-07-05 09:17:57 golinux: So what went wrong? Any tracks in the logs?
You know that the Devuan certs fail regularly
2017-07-05 09:24:13 rrq: afaics nothing in the logs
2017-07-05 09:35:35 rrq: I changed the cron line to make the certbot
invocation log to /tmp/certbot.log
2017-07-05 09:36:12 rrq: the cert is 3 months, so that log will be
interesting in about 2 months

I think part of the problem is that nginx isn't getting restarted. 
We'll be watching our certbot closely till the next renewal.
