He took office on 8 May 2025. Intervals are left-closed right-open and based on calendar days in the Vatican time zone, e.g. if he dies or resigns on 7 May 2035 (regardless of the time of the day) then it resolves "Between 3 and 10 years" whereas if he dies or resigns on 8 May 2035 (regardless of the time of the day) then it resolves "Between 10 and 30 years".

So far, 9 popes reigned for less than 1 month and only 2 reigned for more than 30 years, see https://en.wikipedia.org/wiki/Pope#Lengths_of_papal_reign (but note that that list uses a definition of length which is off by one day with respect to mine).
