Era is a graphical calendar application designed to work equally well for quick everyday scheduling and more involved planning. Its interface is responsive, so it can sit in a small window alongside other applications or expand to provide more space when managing a busy calendar.
The application can synchronise events with supported online calendar providers while retaining offline access. Under the hood, its calendar architecture is modular, with Evolution Data Server providing integration with established calendar services. The interface uses GNOME technologies and is intended to work across both conventional desktop displays and smaller form factors.
This is free and open source software.
