You can organize your events into meaningful and manageable groups using different calendars with unique names and colors. With separate calendars, you can choose to see your events one at a time, a few at a time, or all at once.

To create a new calendar:

1. Go to Yahoo! Mail and select the Calendar tab.
   - If you have "Calendars" collapsed in the left panel, select Calendars to expand it to view your calendars.
   (If the left panel is hidden, select Actions | Left Panel.)
2. Choose the method you prefer to open the "Add Calendar" window:
   - Using the Actions menu: Select Actions | Create New Calendar.
   - Using the + (plus) button in the left panel: Select the + (plus) button to the right of "Calendars."
3. Type a name for the new calendar.
4. Select a color for the calendar.
5. Click Save.

The new calendar is added to your list of calendars in the left panel.
