How to use this month
A peak is an instant, not a night. What matters for you is whether the radiant is high and the sky is dark during the hours you are actually outside, which depends on your latitude and your weather — neither of which a calendar can know. Use this page to pick candidate nights, then check the verdict for your own coordinates on the day.
