Editorial policy and corrections

Travel into town because of a wrong date and you find the doors shut. So this page sets out where each date comes from and what happens when something is wrong.

Order of sources

1. Acts in force on the states’ law portals: the sixteen shop opening acts, plus Art. 140 of the Basic Law;
2. Town decisions: ordinances, bylaws and general orders in the official gazette, notices on the town’s website;
3. Town statements: pages of public order offices and municipal marketing companies, the town’s press releases where no ordinance is online.

Aggregator sites, advertising, shopping-centre pages and newspaper articles are not a source for a date. Where there is no official source we write “not yet published” or “no source”.

Computed where possible

Church-year barred days such as Easter, Whitsun, Advent and Totensonntag are derived from their rules by a calculation core. Automated tests check at every change that each listed date is possible under its state’s act and that every source has a reading date.

Rhythm

Towns are re-read at every update, above all from November to February. A full review of the acts at least every 12 months and after every change in the law.

Handling errors and cancellations

1. Check at the source.
2. Correct or remove the date, with a new reading date.
3. New position on every page and in the calendar file.

Independence

No money from shops, shopping centres, associations or authorities. No affiliate links, no paid content, no lead-generation form.
