Add holidays and events, and share tagged event photos with parents.
Go to Calendar and add holidays, events, exam dates, and parent-teacher meets. It drives the dashboard 'Today' widget and auto-marks attendance holidays.

Under Gallery, upload event photos (auto-resized) and tag them to a grade or section so the right parents see them on their portal.
Tagging keeps photos private to the relevant class, not the whole school.
Parents and staff see the calendar and gallery in their portals.
