2023 Phenology Calendar

Pre-order now!

The 2023 Phenology Calendar adorns the wall with beautiful nature photography and shares average observation dates for many natural phenomena. The calendar is rooted in the Leopold family’s passion for the study of phenology, and features monthly narratives explaining iconic phenological events. Curated by Aldo Leopold Foundation Senior Fellow Stan Temple, the sidebars help explain the seasonal events happening in your backyard and the calendar offers reminders for what you might expect to observe nearly every day of the year.

The calendar presale runs through October 31. Calendars will begin shipping in early November.
