36 days of the year are part of the APD holiday period carveout limiting the use of IVDs. I'd put 10% of the year, and probably well above 10% of total trips touching any of those days as above "very limited exceptions."
Edit to add that APD holiday period days make up 6 of 31 days in Dec this year, or 19.4% of the month, but 36.5% of trips touch them in my BES.
