How it works
Look first at the order of the two signs. A result reading Virgo to Leo means Mercury is moving backward across 0 degrees Virgo, a retrograde re-entry, while Leo to Virgo is the ordinary forward entry. In a constructed sequence, Mercury enters Virgo, slips back into Leo about three weeks later and re-enters Virgo roughly three weeks after that: three ingresses at one boundary in about two months.
Mercury never strays more than about 28 degrees from the Sun, so its sign is always the Sun's sign or one of the two on either side. Astrologers check Mercury ingresses for shifts in the style of conversation, paperwork and trip planning, especially when a retrograde makes Mercury cross the same boundary more than once.
Traditionally Mercury rules Gemini and Virgo and is read as the planet of speech, trade, learning and short journeys. A Mercury sign change is said to alter the tone of thinking and talking, quicker and blunter in a fire sign, slower and more deliberate in an earth sign.
When the result shows a forward entry, jot down one conversation or piece of writing you want to approach in that sign's style. If it shows a backward crossing, use the extra weeks to revisit drafts and unanswered messages.

FAQ
Because current transits change quickly, especially the Moon and the angles. A-grade timing pages need to tell users exactly what moment they are looking at.
Because the product is tuned for practical planning use, including location presets, readable language, and repeat-use context.
Refresh it whenever you want the current sky again, especially if you are watching the Moon, angles, or a fast-moving daily transit picture.
