With a grown-up
One observation challenge
If you are already awake with a grown-up before sunrise, try finding the thin Moon. Draw what you see or write “Moon not visible”. Never look toward the Sun.
Come back tomorrow. Keep your drawing and its date and time on paper so you can compare.
Will we see it from home?
This is a phase calculation, not a local sky or weather forecast. Seeing the Moon depends on your location, moonrise and moonset, clouds, and buildings or hills. The Moon can also be up during daylight. We do not request your location or check your weather.

Astronomy Engine calculates the Moon’s phase and sunlit fraction for the current time. The labels use small windows around new, quarter and full Moon. The time shown switches to your device’s time zone after the page loads; the calculation refreshes every minute.
