Does not the website's use of the Gregorian calendar contradict its fatwa prohibiting it?

The fatwas on this site do not prohibit the use of the Gregorian calendar; rather, they dislike it and prefer avoiding it. What might appear as a prohibition is merely a نقل (transmission) of the sayings of some scholars to present the difference of opinion on the matter, and it is not the relied-upon view in the fatwa. The site primarily uses the Hijri date, followed by the Gregorian date.
