Test a Calendar Subscription Link
Confirm the link works before you share it with 30 people.
Free to run, no account needed. The first two weeks of the schedule sync to any calendar app for good. $5 covers the rest.
A calendar link that does not load is a silent failure. The creator does not see the error. Anyone who added it sees an empty calendar or no events at all.
Calfeed tests every link you publish. Loadable. Valid events. Correct time zones. Refreshable. You see green before you share it. Handy if you publish from the plain-text or merge-calendars tools.
Anyone who added it sees a calendar that works on day one. You see fewer support questions. For getting the link onto 30 phones cleanly, see how to share a calendar with a group.
