Use **Calendar Sync** to subscribe to your personal Leadtime calendar in Google Calendar, Outlook, Apple Calendar, or any app that supports an iCalendar ICS web feed. Pipeline items assigned to you appear as events.

---

## Where to find it

Open **My Profile** from your profile picture or the sidebar, then choose **Calendar Sync**.

---

## What is synchronized

The feed shows **your** Leadtime Pipeline assignments as external calendar events. If Leadtime adds more event types later, the same subscription URL will include them automatically.

- Works with “Subscribe from URL,” “From the internet,” and comparable ICS subscription features.
- Each calendar provider refreshes the feed on its own schedule.

---

## Subscription link

Copy the address under **Subscription link** and paste it where your calendar app requests a web, ICS, or calendar-by-URL subscription.

Use the **Copy** button to avoid typing errors.

---

## Regenerate the URL

If the link was shared accidentally or you want to revoke previous subscriptions, select **Regenerate URL**. The old address stops working, so update every calendar that still uses it.

:::warning
Treat the subscription URL as a secret link. Anyone who has it can read event titles and times until you regenerate it.

## Set up the subscription

Leadtime provides short instructions for Google Calendar, Outlook / Microsoft 365, and Apple Calendar. Each uses the same subscription URL.

### Google Calendar

- Open Google Calendar in a browser.
- Go to Settings → Add calendar → From URL.
- Paste the subscription URL and confirm.

### Outlook and Microsoft 365

- Open Outlook on the web or desktop.
- Choose Add calendar → Subscribe from the internet. The wording varies by version.
- Paste the URL and save.

### Apple Calendar

- On Mac: File → New Calendar Subscription.
- On iPhone or iPad: Settings → Calendar → Accounts → Add Subscribed Calendar.
- Paste the URL and adjust the refresh interval or display name if needed.

---

## Import busy time from other calendars

Under **Import**, add one or more **HTTPS iCalendar URLs (`.ics`)** from Google Calendar, Outlook, Apple / iCloud, or another provider. Leadtime stores **only free/busy information**, not event titles, so subjects remain private. Busy blocks appear in **Planning → Pipeline** and related views, helping planners avoid booking you twice.

## Get an ICS link

The cards in Leadtime show where each provider exposes the address. Paste it under **Add calendar**.

### Google Calendar

- Open Google Calendar in a browser and choose a calendar under “My calendars.”
- Select its three-dot menu → Settings and sharing.
- Under “Integrate calendar,” copy the secret address in iCal format over HTTPS. Treat it like a password.

### Outlook and Microsoft 365

- Open Outlook on the web and go to Calendar.
- Open Settings → View all Outlook settings → Calendar → Shared calendars.
- Under “Publish a calendar,” choose the calendar and visibility, then copy the link. Availability depends on your organization.

### Apple Calendar and iCloud

- Open the calendar on icloud.com and select the relevant calendar.
- Use the sharing icon and enable a public or shareable link if necessary.
- Copy the HTTPS or `webcal` address. If no link is available, check Calendar sharing on a Mac or ask your administrator.

The **Linked calendars** table shows every feed, its latest synchronization, and status. Edit a name or URL, or remove a feed when its busy time should no longer appear in Leadtime.
