Your calendar on nostr
If you publish your calendar's events on nostr (NIP-52) from your own key, the index lists it on its own as it reads the relays, and serves your events as iCalendar, jCal and JSON-LD. The index signs nothing for it. Sign in with your key to list it now, from your own relays, and to say where its events are.
Sign in with your nostr key
Your nostr browser extension (NIP-07) signs each request for this page alone. Your key never leaves it.
To remove it, open its page once it is listed and manage it with the same key.
