That naming convention would not hold up, I'm afraid. Although Ramadan occurs 
during northern-hemisphere summer this year, the Islamic calendar is lunar and 
does not stay in sync with the Gregorian calendar, and by 2026 Ramadan will be 
occurring during northern-hemisphere winter.

We don't have to worry about inventing a naming convention for this in tzdb, as 
it is using the labels +01 and +00 for time in Morocco.
