When is Ramadan 2028?

Ramadan is fixed in the Hijri calendar, which is purely lunar with no leap month at all. Twelve lunar months run about eleven days shorter than a solar year, so the Gregorian date walks steadily backwards through the seasons and returns to the same point roughly every thirty-three years — 11 days earlier than in 2027.

Which dates fall near Ramadan changes every year, because the calendars move against each other.
