I don't think it's one a day, but given the number of 737NG's out there, the number of hours per month is huge (someone quoted me a number many years ago - it was something on the order of a million engine hours/month). That means you could have 10 shutdowns/month (i.e. 1 per 100,000 hrs.) and still meet the shutdown rate for 180 minute ETOPS...
