Mercury, being the Planet that stays closest to the Sun, never strays more than about 28 degrees from the Sun. This means Mercury is often found in the same sign as the Sun or in the adjacent signs.

Mercury is known for its swift movement through the zodiac. Typically spending about 23-30 days in each zodiac sign. However, due to Mercury's retrograde cycles, the duration in a single sign can vary from 15 to 60 days.

It's important to note that Mercury's transit through the zodiac signs is not always uniform due to its eccentric orbit and retrograde motions. These factors can cause Mercury to spend varying amounts of time in different signs, making its journey through the zodiac more complex than a simple, evenly-divided cycle. Therefore it is easiest to say it takes around 1 year to complete it’s cycle through the 12 Zodiacs.

Around 1 Year to complete its cycle.
15 - 60 Days to transit through 1 Zodiac sign.
Compare with the Sun which takes 30 Days to transit 1 Zodiac Sign.

Word’s of Henry Cornelius Agrippa
