AAS Wall Calendar

2021 Wall Calendar

Due to the ongoing coronavirus pandemic, many of us have transitioned to home-based telework; therefore, you may have received an email from us asking your best mailing address (if you wish to receive a printed copy of our 2021 wall calendar).

This is a onetime request, and your member record will NOT be impacted by this change.

Deadline: 1 September

One of the many benefits of membership in the AAS is the annual AAS Wall Calendar. It is provided free to all members and makes an attractive addition to any office. The calendar highlights important astronomical events month by month, including AAS and Division meetings, proposal and grant deadlines, solar and lunar eclipses, equinoxes and solstices, meteor showers, Moon phases, and more. Produced in standard format, the calendar measures 12 x 9 inches closed, 12 x 18 inches open.


Each month of the AAS Wall Calendar affords an opportunity for sponsorship by an observatory or other astronomy-related organization, department, mission, or project. Sponsors are featured with a full-page photo or illustration of their choosing, one or more logos, and a short block of text including a caption and credit. Sponsorship of the AAS Wall Calendar is a great way to show your support for the astronomical community and to ensure that your project, mission, or institution is recognized by astronomers all across North America.

Space is provided on a first-come, first-served basis. Anyone interested in sponsoring a month in next year's AAS Wall Calendar should contact Crystal Tinch for more information and pricing. Deadline: 1 September of the current year.

Dates & Deadlines

The AAS relies on meeting organizers, telescope-allocation committees, funding agencies, foundations, and others to inform us of key dates and deadlines for inclusion in the AAS Wall Calendar. Every year we're asked why a particular proposal deadline or other important event of widespread interest to AAS members wasn't listed in the calendar, and the answer is always the same: "Because nobody told us about it." Don't let this happen to you! Please forward any key dates and deadlines for next year's AAS Wall Calendar to Crystal Tinch as soon as possible. Deadline: 1 September of the current year.

Birthdays in the AAS Wall Calendar

Nearly all the astronomers whose birthdays are noted in the AAS Wall Calendar are white men. We explain why that was true in the past and invite you to help us celebrate more women and people of color in the future.
