Sync your TaskCalendars events with your favorite calendar applications using iCal feeds.

What is iCal?

iCal (iCalendar) is a universal calendar format supported by virtually all calendar applications. TaskCalendars provides an iCal feed URL that you can subscribe to in Outlook, Google Calendar, Apple Calendar, and other apps.

Setting Up Your Calendar Feed

Step 1: Configure Your Feed

  1. Click your profile icon in the lower left corner
  2. Select App Settings
  3. Scroll to the Calendar Sync (iCalendar) section

Step 2: Choose Your Options

Configure how your feed works:

  • Filter Preset - By default, your feed includes all tasks you have access to. Select a filter preset to limit which tasks appear in your external calendar.

  • Include completed tasks - Check this box if you want completed tasks to appear in your calendar feed.

  • Months ahead to include - Choose how many months of future tasks to include (1-24 months).

Step 3: Create a Filter Preset (Optional)

To create a filter preset for your calendar feed:

  1. Go to the Calendar or Kanban view
  2. Use the filter panel to select specific calendars, tags, and labels
  3. Click the bookmark icon to save your filters as a preset
  4. Return to App Settings and select your preset

Step 4: Get Your Feed URL

After configuring your options, you’ll see your Calendar Feed URL. You have two ways to add it:

  • Quick add: Click “Add to Calendar” to open your default calendar app automatically
  • Manual: Click “Copy URL” to copy the feed URL, then paste it in your calendar app

Important: Your feed URL is private and unique to you. Don’t share it publicly as it provides access to your calendar data.

Sync Settings

Refresh Frequency

External calendars typically sync on a schedule:

  • Google Calendar: Every 12-24 hours
  • Apple Calendar: Configurable (5 min to daily)
  • Outlook: Every 3-24 hours

For more frequent updates, check your calendar app’s sync settings.

One-Way Sync

iCal feeds are read-only. Changes made in TaskCalendars will sync to your external calendar, but changes made in your external calendar will not sync back to TaskCalendars.

Troubleshooting

Events Not Appearing

  • Wait a few hours for the initial sync to complete
  • Try removing and re-adding the calendar subscription
  • Verify the feed URL is correct and accessible
  • Check that your filter preset includes the tasks you expect

Duplicate Events

  • Check if you’ve subscribed to the same calendar multiple times
  • Remove duplicate subscriptions from your calendar app

Events Outdated

  • Check your calendar app’s refresh settings
  • Manually refresh the calendar subscription
  • Some apps have a minimum refresh interval

URL Not Working

  • Ensure you copied the complete URL
  • Check your TaskCalendars account is active
  • Return to App Settings to verify your feed URL

Security Best Practices

  • Keep your feed URL private - Anyone with the URL can view your calendar
  • Use filter presets - Limit exposed data by only including necessary tasks
  • Use HTTPS - The feed URL always uses secure HTTPS connections
