Calendars help you organize your events into separate groups like "Personal", "Work", or "Family". Each calendar has its own color, making it easy to see at a glance what type of event you're looking at.

Create a new calendar

Ready to add another calendar? Here's how:

  1. In the app sidebar, find My Calendars
  2. Click the + menu button
  3. Choose Create new calendar
  4. Pick a name and color that works for you
  5. Save, and you're done!
Free plan limit
The Free plan includes 1 calendar. Need more? Upgrade to Plus to create unlimited calendars for different parts of your life.

Add a built-in holiday calendar

Need a public holiday calendar for a country or region you care about? Open the + menu in My Calendars, choose Add holiday calendar, then pick a country or region from the list.

Built-in holiday calendars are managed by NimbleCal, so you can change their color, visibility, and reminder defaults, but you cannot rename them or edit the holiday events directly. After you add one, it appears in its own Holiday Calendars section in the sidebar instead of under My Calendars.

Holiday coverage
Built-in holiday calendars include the current year plus the next two years of public holidays. NimbleCal refreshes that data automatically, so you do not need to re-add the calendar each year. If you are planning further ahead, later holidays will appear as newer first-party holiday data is published.

Rename or edit a calendar

Want to change your calendar's name or color? Easy:

  1. In My Calendars, hover over the calendar you want to edit
  2. Click the ... (three dots) menu
  3. Choose Edit calendar
  4. Update the name, color, or default reminder settings
  5. Save your changes
Pro tip
Use different colors for different calendars so you can instantly recognize event types at a glance. For example: blue for work, green for personal, orange for family.

Set your default calendar

Your default calendar is where new events go when you create them quickly (like from Quick Add or a simple click on the calendar grid).

To change which calendar is your default:

  1. Open Edit calendar for the calendar you want to make default
  2. Enable Set as default calendar
  3. Save

Now all new events will automatically go into this calendar unless you specify otherwise.

Delete a calendar

Need to remove a calendar? Here's how:

  1. Open the calendar's ... menu
  2. Choose Delete Calendar
  3. Confirm the deletion
Can't delete your last calendar
NimbleCal requires at least one calendar to work. If you want to start fresh, try renaming your existing calendar instead of deleting it.
