Egypt plan to [cancel] DST during Ramadan and then to resume DST again.

6:08 am is the time of the new moon, not the time that the crescent
will appear. The crescent moon that marks the beginning of the Muslim
month can only be seen in the evening.  It would be first visible on
the evening of August 10 or 11.
suggests it will be August 11 for the Middle East.  This suggests the
Ramadan would begin on the evening of August 11.  It seems, then that
they will make the switch about 18 hours before the beginning of
Ramadan, which seems quite reasonable.  However, according to
wikipedia, Ramadan starts on August 10.  Other websites show it
starting on August 11.  Go figure.  The first full day of Ramadan, by
the traditional definition, should be August 12.
