Nights on Earth 2025 Calendar and Stargazer's Guide to the Night Sky

New for 2025: Astronomical Times Customized to Your Location!

I'm incredibly proud to announce that for the first time, Nights on Earth is available in both the Classic Edition (astronomical times are calibrated to Lake Tahoe, CA as they have been in previous years) OR the Custom Edition with astronomical times customized to your location anywhere on earth!! The Custom Edition may be ordered from this page, or keep reading to learn more.

Nights on Earth 2025 is a 12-month fine art wall calendar and stargazer's guide to the night sky, from astro-landscape photographer Phil Mosby. As much an Almanac as it is a traditional wall calendar, Nights on Earth contains a plethora of interesting space and astronomy-related facts and datapoints accompanied by 12 awe-inspiring Nightscape photos. Meticulously researched and gorgeously printed on heavy paper stock, Nights on Earth is a unique, interesting, and functional gift for any space, science, nature, or photography lover!

Specs: 12" x 12" (12" x 24" when open) full-size wall calendar, beautifully printed on heavy paper stock in Reno, NV.

Absolutely love your Nights on Earth calendar-- it's just gorgeous.

Absolutely love your Nights on Earth calendar-- it's just gorgeous. I love being able to see the sunrise/sunset times and all of the astronomical events happening. My first purchase was the 2023 calendar but you can count me for a customer for life after this. I love having a piece of art to display in my office for myself and others to gaze at.

Beautiful work, great print quality--just an exceptional calendar. Read MoreRead Less

...Plus the images are gorgeous!

I love being able to see at a glance what astronomical events are happening on any given day. It is much preferred to trying to google the information and having to sort through results. Plus the images are gorgeous! Read MoreRead Less

I love astronomy and it's so satisfying not having to look up on Google about the day

This year has been eventful and I've never used a calendar before this year. It's nice to look back and see those events. I've been able to plan my days better. Even the little things like knowing when to take my dog out before it gets dark. I love astronomy and it's so satisfying not having to look up on Google about the day, it's right on the calendar. The pictures are beautiful and the random facts that I've added too my arsenal daily is satisfying. Read MoreRead Less

I love the layout of each day and the facts, and most of all the photos!

Your calendar is the most amazing calendar I've ever owned. I love all things to do with outer space and I've always especially loved keeping track of meteor showers and other space events.

With your calendar, I don't even have to look up dates or anything! They're just right there for me to be excited about. I love the layout of each day and the facts, and most of all the photos!

You take astonishing photos my friend, and I get excited whenever I have to flip the calendar to a new month and see another beautiful photo!

I am so excited to order next year's! Keep it up! Read MoreRead Less

Thank you so much for taking the time to do this. Your photos are amazing.

My son was just telling me to check and see if you were going to make one for 2023! We both really enjoyed your 2022 calendar, even though we don’t have darkness in the summer where we live. Thank you so much for taking the time to do this. Your photos are amazing. Read MoreRead Less

I have the 2022 calendar and I love it!

I have the 2022 calendar and I love it! The pictures are amazing and all of the astronomical info is super helpful. I use it to plan camping trips around the best stargazing times and to plan daily outdoor activities since it gives sunrise / sunset times. I will definitely be ordering a 2023 for myself and a few more for Christmas gifts. Read MoreRead Less

This will be my third, and I use it daily as my astro bible!

Just a quick note of thanks for the work I know you put into your fabulous calendar! This will be my third, and I use it daily as my astro bible! I've only been shooting nightscapes for a couple years, so your work is invaluable to me. Thank you for your commitment to this wonderful and beautiful resource! Read MoreRead Less

This IS the night sky calendar you're looking for!

Holy cow! This is one beautiful piece of form and function! Every page is elegantly laid out with gorgeous imagery and loads of useful night sky condition information! All calendars have moon phases, but this one clearly and conveniently indicates a waning moon with a clever dark sky graphic on the appropriate days, making optimal dark sky viewing sessions easy to plan at a simple glance! Very cool! 😎 Upon closer inspection there is sun & moon, rise & set times for everyday. Meteor showers, conjunctions, and eclipses all there. Even planet AND Milky Way visabilty! Whoa! Creator really went above and beyond with this one! Maybe too much so as it continues FULLY ILLUSTRATED into first quarter of 2022! You really get more than your money's worth on this one. Only reservation I have would be I wish it were a little bigger, maybe 14x14". Text is a bit small and hard to read for us older folk and images really deserve to be that much more showcased. Really hope this calendar series continues because it's my new go to! Great job, Phil Mosby. You are a rock Star! Read MoreRead Less

The pictures in this calendar are works of art

You don't have to be an astronomy fan to enjoy this calendar. Every single photo is amazing. If you do want to know what there is to see in the night sky that can be answered by this calendar too. I highly recommend this for yourself and it also makes a great gift. Read MoreRead Less

Awesome & Perfect gift!

These calendars are beautiful and educational! They have a ton of info about star gazing, but also artistically captures the night sky and Tahoe landscape—seriously, what could be better? I have several pieces from this artist, but having a calendar is like having a new piece of art each month. This year all my family members are getting one for x-mas! Read MoreRead Less
