Sources and data
Where the dates come from and what verified means.
We transcribe dates only from the collection calendar the town published itself, usually a PDF. We take nothing from the prose on a town’s website, even when dates appear there.
Verified means we transcribed the calendar from the source and checked it. When the calendar’s year ends it turns unverified, even if nothing in it changed. The data stays visible, we just no longer vouch for it.
2,805 of 2,926 towns are processed, or 95.9 %. The register holds 4,686 units: 2,926 towns and 1,760 city districts. Transcription runs per town, so the denominator is 2,926, not 4,686.
District and town boundaries come from geoBoundaries (gbOpen), © OpenStreetMap, licence ODbL 1.0. We state it here, not only on the map: the licence requires it. The licence covers the boundary file itself: anyone who reuses it names the same source under the same licence.
The dates come from public municipal documents, but finding, transcribing and verifying them is our work. The Vynes kôš database is therefore protected by the sui generis database right under Slovak copyright law (Act No. 185/2015 Coll.). Anyone may look up their town and subscribe to its calendar for free. Bulk extraction or republication of a substantial part of the database without consent is not permitted; to use the data, reach out via Report an error.
The Report-an-error form and data reads are protected from bots by Cloudflare Turnstile verification, which does not track users across sites. What Cloudflare processes during a check is described in the Turnstile Privacy Addendum.
Where we stand
As of 5 Sep 2026. Towns researched: 2,926.
“Still looking” does not mean no calendar exists. The town does have a collection round; we simply have not found its published calendar yet, and we keep looking.
Found a difference?
If our date doesn’t match your town’s calendar, write to us and include a link to the source. Without a verifiable source we don’t take data on.
Report an errorWhat we have transcribed
Three different questions, never merged. towns = whether the town collects this type at all. series = how many independent schedules exist in the country; a zoned town has more than one. on the map = how many towns yield an annual number the map can colour. The first and third columns count towns, the second counts schedules, so series can run above or below towns.
