When the ghost or spirit of the number π would appear to some lucky mathematicians or math educators to reveal to them some of her sexy numerical, geometric, or trigonometric properties—when they least expect her to visiting them, while experiencing an aha!
Unlike demonic apparitions that petrify even diehard Proud Boys “patriots,” pi apparitions are welcomed by both the mathematical brethren and the numerological fraternity.

pi = approximately 3.14
therefore, when the clock shows 3:14, it is Pi Time!
An excellent time to eat pie.

When the public announcement of the proof of a famous unsolved problem on π turned out to be short-lived, because the result was later found to contain grave errors.
Mathematicians worldwide were excited to hear that the number (π + e) has been proved to be transcendental (i.e., its value can’t be the root of an algebraic equation with rational coefficients), but the news was nothing but a pi moment.
