What this means for you

A transit is only half the picture. The same Mercury movement lands differently for each person, because what matters is which house it occupies counted from your own Moon sign or ascendant. In the tool you can pick your Moon sign, or enter your birth details, and the same dates are recast as houses in your chart, with classical patterns such as Sade Sati marked automatically.

• Drag the year timeline to any date and watch the chart follow.
• Jump straight to the next or previous sign change.
• Compare Mercury with up to two other planets to find where their paths cross.
• Print a transit report or export the whole year as a spreadsheet.
