Domain Drop Calendar
Put your domain expiry and predicted drop dates in the calendar app you already check every day. Subscribe once, and every monitored domain shows up as an all-day event.
What the feed gives you
The calendar feed is a read-only iCalendar subscription. For each domain you monitor, it adds an all-day event on the expiry date and, when we can predict one, an all-day event on the estimated drop date with the prediction confidence in the title. Every event names the registrar and links back to the domain in your dashboard.
It is one URL, private to your account, and it updates as your domains do. There is nothing to install. You enable it from your settings and paste the link into your calendar app.
How to subscribe
Apple Calendar
Enable the feed in settings and click the webcal:// link, or in Calendar choose File > New Calendar Subscription and paste the https link. Leave "Remove Alerts" unchecked to keep the expiry and drop reminders.
Google Calendar
Open Google Calendar on the web, go to Other calendars > From URL, and paste the https link. Google shows the events but not the alarms, so lean on your shadom.co notifications for the actual reminders.
Thunderbird, DAVx5, and others
Any app that reads a remote iCalendar URL works: add a network calendar and paste the https link. On Android, DAVx5 can carry the subscription into the system calendar. Refresh cadence is whatever the app allows you to set.
Client support, honestly
Subscribed calendars are not equal. Two things vary by client: whether reminder alarms survive, and how often the calendar re-fetches the feed. Refresh is always client-controlled. The feed asks for a 12-hour refresh, but that is a hint clients are free to ignore.
| Client | Subscribe | Alarms | Refresh |
|---|---|---|---|
| Apple Calendar (macOS, iOS) | Yes, open the webcal:// link | Kept if "Remove Alerts" is unchecked | Defaults to weekly; adjustable per subscription |
| Google Calendar | Yes, Add calendar > From URL (https link) | Stripped from subscribed calendars | Google-controlled, roughly every 12 to 48 hours |
| Thunderbird | Yes, New Calendar > On the Network (https link) | Kept | Configurable interval you set |
| Outlook (web/desktop) | Yes, Add calendar > Subscribe from web | Not shown for subscribed calendars | Microsoft-controlled, not user-settable |
Frequently asked questions
What events does the calendar feed contain?
One all-day event for each domain expiry date, and one for each predicted drop date, labelled with the prediction confidence. Each event carries the registrar and a link back to the domain in your dashboard. Domains with no known expiry date, and domains that have already dropped, are left out.
How often does the calendar update?
That is controlled by your calendar app, not by shadom.co. The feed suggests a 12-hour refresh, but clients treat that as a hint. Google Calendar typically re-fetches every 12 to 48 hours, and Apple Calendar defaults to weekly (you can lower it in the subscription settings). There is no way for the feed to force an immediate refresh.
Will I get reminder pop-ups from the calendar?
Sometimes. The feed embeds alarms 7 days and 1 day before expiry, and 1 day before a predicted drop. Apple Calendar honors them if you leave "Remove Alerts" unchecked when subscribing. Google Calendar strips alarms from subscribed calendars entirely. Either way, your shadom.co email, push, and webhook alerts are the reliable reminder channel; treat calendar alarms as a bonus.
Is the feed URL private?
The URL contains a private token that acts as the password to your feed, so anyone with the link can read your domain list, dates, and registrars. Do not share it or post it publicly. If it leaks, regenerate it from settings, which instantly revokes the old URL.
Do you support CalDAV?
Not yet. The current feed is a one-way subscription (the calendar reads it, nothing writes back). Native CalDAV sync is on the table if enough people ask; email us and describe your setup.
