Assuming that the point concerns a February when the first day of the month is Sunday, and the entire month is composed of 4 full weeks with no days overlapping into a partial week...

2017 is not such a year. (2015 was) But...

if you click on your computer's calendar, set the month to February, then cycle thru the years, the following years all show February starting on a Sunday, having 4 weeks of contiguous Sunday-Saturday and no overlap into a partial week:

2026
2037
2043
2054
2065
2072
2082

I could go on, but this makes the point that the frequency is demonstrably much more than once every several hundred years.
