If you want the fasting rules for a given day, the Orthodox Calendar here has them: https://www.holytrinityorthodox.com/htc/orthodox-calendar/

They also have an Android and iOS app for the calendar: https://www.holytrinityorthodox.com/htc/orthodox-calendar/android-app/

There is also a printable wall calendar available here that we downloaded and got color printed on 11x17 pages from staples: https://churchofthedormition.com/revfrpaulfefelovscalendar
