The order of the flats is:
B, E, A, D, G, C, F
The first four flats spell
BEAD. I used to
remember
British
European
Airways
Do
Good
Continental
Flights which
probably once was true but BEA no longer exist anymore.
British European Airways Do
Good Continental Flights

F, C, G, D, A, E, B are the order of the sharps.
Try and remember a phrase like this one for the order of the
sharps:
Fat
Cats
Go
Down
Alleys
Eating
Birds.

Have you noticed that the order of the sharps is the same as
the flats only backwards!
BEADGCF ↔ FCGDAEB

Look at the piano keyboard and notice how the order of the
flat keys (F-Bb-Eb-Ab etc.) move down from middle C in
perfect 5th intervals whereas the sharp keys do the same but
ascending (G-D-A-E etc.) This is the Circle of 5ths.
The sharps and flats do exactly the same.
Minor Keys
To work out the minor key signatures then first think of the
tonic or parallel major and subtract 3. Say you need to know
C minor. First think about C major. C major has a value of
0. Subtract 3. Your result is -3. Minus 3 means three flats.
So C minor has three flats. Now remember the order B-E-A. So
C minor has Bb, Eb and Ab.
If you need to work out a more difficult minor key say F#
minor for instance, then start with F major. Add 7. -1 +7 =
6 so F# major has 6 sharps. Then subtract 3 (ending up with
F# minor = 3 sharps)
I'll need to have a rest now....I think I've worn my brain
out! SORRY!
