Pagan Calendar shows events from pagancalendar.co.uk on your phone. Events include equinoxes, solstices, planetary ingresses etc. Clicking on an event gives you the event information.
You can select your timezone from the settings, adjusting times for events with times, such as the summer solstice.
There is a pro version of the app in-case you want a widget for your phones home screen, or if you just wish to support the developer.
Hemisphere menu option, sidereal spelling fix, re-import timezones option, bug fix for when no events to download.
