For Egypt in 2017 Ramadan is predicted to start about May 27 Sat, a
month after DST is scheduled on Apr 27 Thu, so not so short a period.
Eid starts in Shawwal about Jun 26 Mon, so DST would not then start
until Jun 29 Thu if they keep to the same day, or they could start
DST right after Ramadan, a delay of 2 months in either case.
Ramadan starts about 11+-1 days earlier each year, so delaying DST
start in 2018 and especially 2019 would make more sense, but in each
case that would delay DST by more than a month.
In 2020 Ramadan starts only a day or two after DST is currently
scheduled, so that delay is very likely, but when DST starts would
likely depend on what they do this year and the next few, or as usual,
on the whims of the politicians involved at the time. ;^>
For 2036 on, it seems more likely that they would end DST sooner by
a couple of weeks each year.
