Mercury's sign describes a style of thought and speech; its house describes the life setting where that style may be expressed. Both belong to a whole chart. These articles use the tropical zodiac and explain Whole Sign context while allowing other house systems.

How to find Mercury's house

Use an accurate birth date, local time, birthplace coordinates, and the historical UTC offset. Choose a house system and record it with the result. In Whole Sign houses, the rising sign is the entire first house and each following zodiac sign becomes the next house. Another system may place Mercury in an adjacent house, especially near a boundary. An unknown birth time does not support a reliable house claim.
