nostr-calendar

Fetch events from an ICS + RSS feed and publish them as NIP-52 calendar events (kind 31923) to Nostr relays, requesting inclusion in a kind 31924 calendar.

Install

Clone this repository to /opt/nostr-calendar:

sudo git clone <repo-url> /opt/nostr-calendar
sudo chown -R "$USER:$USER" /opt/nostr-calendar
cd /opt/nostr-calendar
./install.sh

The installer creates a virtualenv, installs dependencies, and copies config.toml.example to config.toml.

Configure

Edit config.toml and set at minimum:

secret_key — your Nostr secret key (nsec1... or hex)
relays — relays to publish to
calendar.d, calendar.title, calendar.description — your calendar

Then lock down the file:

chmod 600 config.toml

Test

/opt/nostr-calendar/venv/bin/python /opt/nostr-calendar/publish.py

Check the output and publish.log. On the first run, all events are published; subsequent runs only publish new or changed events (dedupe is tracked in events.db).

Schedule with cron

crontab -e

Add:

*/30 * * * * /opt/nostr-calendar/run.sh >> /opt/nostr-calendar/cron.log 2>&1

This runs every 30 minutes. Adjust the */30 to taste.

Notes

config.toml contains your secret key and is gitignored. Never commit it.
The virtualenv is not relocatable — if you move the directory after installing, recreate the venv by re-running ./install.sh.
The only place the absolute install path appears is the crontab entry.
