Activities are events, exams, birthdays, or any important dates you want to track. Each activity can have:

• Title and description
• Date and time (or all-day events)
• Activity type (Birthday, Exam, Event, etc.)
• Location (for events like birthdays)
• Study material (for exams)
• Reminder settings (days before the event)

To create an activity:
1. Navigate to a space
2. Click 'Add Activity'
3. Fill in the activity details
4. Set reminder preferences
5. Save the activity

All members of the space will receive push notifications based on your reminder settings. You can edit or delete activities if you have the appropriate permissions.
