tulsacal

A trustworthy local-events data utility for Tulsa — source intelligence, freshness, dedupe, and provenance you can verify.

Not a prettier calendar grid. Every event below links back to the source that reported it, with a confidence tier and when it was last verified.

{ } events.json ↓ download .ics ? how to reuse this

# browse events

Filter the canonical event set. Filter state lives in the URL, so any view is a shareable link.

# source registry

TulsaCal weights official venue / organizer / city sources above aggregators, and labels social posts as sightings until a stronger source confirms them. Coverage, not curation, is the moat.

# how this data is built

Observations (what a source said, when) are stored separately from canonical events (what the calendar currently believes). Duplicates merge; events never silently disappear.

# data & api

The product is the data. Reuse it.

license & attribution

Thin factual event records. TulsaCal's compilation is published under CC BY 4.0; each record links to its primary source.

Attribute as: “Event data compiled by TulsaCal (CC BY 4.0); source: <venue>.”
Per-source rights are tracked in the registry.
Aggregators are used for discovery only, then traced to a primary source.

what this is not

Not a hand-curated “best of” calendar.
Not a place that silently deletes events when a source drops them.
Not scraping social without provenance — social posts are labeled sightings.

It’s the source layer the calendars are built on.
