Know the best nights of any year to photograph the Milky Way in your location

Get a personalized Milky Way calendar for any location, with the best dates, visibility times, moon phases, and the angle of the Galactic Center to help you plan your compositions with precision.

What we need from you

What you Get

For every Saturday* of your selected year, your custom calendar includes:

Moon illumination, moonrise, and moonset
Sunset and sunrise times
Milky Way start, end, and total visibility time
Galactic Center visibility: start, end, and total time
Galactic Center average elevation to help plan vertical or panoramic compositions
All times are shown in the local time of your selected location

Note*: To keep the calendar clear and printable, it shows Saturdays only. You can easily estimate the surrounding days, as conditions are usually very similar within a couple of days before and after each Saturday.

Important information before purchasing

This platform works with credits. You can purchase individual credits or a bundle of 5 at a discount. Each credit allows you to generate one calendar.

Calendars show Saturdays only to keep them clear, easy to read, and printable. Nearby days will have very similar conditions.

Your calendar may take up to 5 minutes to generate. Once ready, it will be available in your account for download for one year from the generation date. After that period, a new purchase will be required to access it again.

We only store calendars for current and future years, not past years. We recommend saving your calendar locally, especially if you’d like to keep past-year calendars for future reference.

Please double-check your inputs: year, coordinates, and location name. If incorrect information or an incorrect coordinate format is provided, a new purchase will be required. No refunds will be issued for incorrect inputs.

Polar regions above 66.5° North or below 66.5° South latitude are not supported.

How to get the correct coordinates format in 3 easy steps

Find your exact location in Google Maps (Desktop)

Right click on the location to display the coordinates

Click the coordinates to copy them to your clipboard

*You can also find coordinates in the Google Maps mobile app, but there is no direct way to copy them. Typing them manually can lead to input errors. Other mobile apps, like Maps.me, are better alternatives because they let you copy coordinates directly.

The final result should look something like this: 36.2350298733245, -116.77082298179006, with at least 6 decimal places for better accuracy. Coordinates must be written in decimal degrees, using a period for decimals and a comma to separate latitude and longitude. The first number is the latitude and the second number is the longitude. A negative number means south for latitude or west for longitude.
