There is a lot of information in traditional Key Signatures. Unlocking the principles in this circle leads to a better understanding of music work.
A key signature is a series of sharp or flat symbols placed on the staff, designating the notes that are to be consistently played higher or lower than the equivalent natural notes. Key signatures, generally written immediately after the clef at the beginning of a line of musical notation. Each major and minor key has an associated key signature that sharpens or flattens the notes which are used in its scale.

What the Heck Can I Do With This?
The Circle of Fourths/Fifths, is the order of the sharps (♯) and flats (♭) that are the 15 major and their relative minor keys that comprise the majority of songs and chord progressions that we encounter. Giving us a way to memorize the order of the 18 major scales and their derived modes .
If there is a secret decoder ring for remembering some of the principles of music — this is one of them.
Here are a few ways to tackle memorizing this order of keys.
First: It's Just an Alphabet
And this is something you already know. Music uses the first seven letters of the alphabet: A B C D E F G . It then just starts over at A and keeps going over this A B C D E F G cycle. You've alrady know this for quite a long time.
Order of Sharp (♯) Keys
Order of sharps (♯) in the major/relative minor keys: F♯ C♯ G♯ D♯ A♯ E♯ B♯ C♯ . It goes from no sharps for the key of C Major to all seven notes sharped for the key of C♯ Major . Two of the three easiest keys/major scale notes to memorize.
Order of Flat (♭) Keys
Order of flats (♭) in the major/relative minor keys: B♭ E♭ A♭ D♭ G♭ C♭ F♭ . It goes from no flats for the key of C Major to all seven notes flatted for the key of C♭ Major . Two of the three easiest keys/major scale notes to memorize. The third of the three easiest keys/major scale notes to memorize.
A Few Things to Notice
Beyond this it's off to Harmonic Analysis for Scale Selection and Chord Substitution – where this information is a valuable tool. A lot of chord progression, i.e., songs move around this cycle.
