What it is
A transit is what the sky is doing right now, laid over the sky you were born under. Your birth chart is fixed; the planets keep moving. When a moving planet reaches a sign, house or aspect that is meaningful in your chart, astrologers call that a transit and read it as a period with a particular flavour.
Transits run at very different speeds. The Moon crosses your whole chart in about a month, so lunar transits last hours. The Sun, Mercury, Venus and Mars take days to weeks. Jupiter and Saturn linger for months; the outer planets can sit on one point for a year or more.
The slow ones tend to get the dramatic write-ups. The fast ones — above all the Moon — are the ones you can actually observe day to day.
Why it matters for daily reflection
A transit is a date on the calendar with a mood attached, which makes it a good excuse to look. "Saturn is squaring my Sun this season" cannot be verified. "I keep noticing I want to cancel plans this week" can. The transit gives you the question; your life gives the answer.
Daily practice works best at Moon speed. A lunar transit over your natal Venus or Mars is short enough to watch begin and end, and the small scale keeps the whole thing honest. Nothing has to happen. You are only checking whether something did.
In Lunara
The daily loop in Lunara is built on the fastest transit of all: today's Moon read against your birth chart, which becomes your Signal. Lunara+ includes transits more broadly, extending the view past the Moon to the slower planets. Whichever tier you use, the evening Echo is where you record what a transit actually felt like — and over time the Resonance Map shows whether a pattern held.
