Time zone boundaries (timezone-boundary-builder 2026c)

Licence : ODbL 1.0 (texte de la licence)

Time zone suggestions use boundary data © OpenStreetMap contributors, ODbL 1.0, via timezone-boundary-builder 2026c. The time zone printed on a sheet is the one its buyer selected from the public-domain IANA time zone database.

⚠ COUNSEL: review of the ODbL produced-work severance argument (user-confirmed selection off public-domain tzdata), and whether compiling the boundary data into the binary constitutes conveying the database. Both are owed before the first paid sheet.

LocationIQ

Licence : Vendor terms of service (texte de la licence)

Geocoding and map tiles by LocationIQ. Location data © OpenStreetMap contributors, ODbL 1.0.

NOAA CO-OPS tide predictions

Licence : Public domain (US Government)

Tide times are synthesised from harmonic constituents published by NOAA's Center for Operational Oceanographic Products and Services, for the station nearest the sheet's coordinates. Tide columns are offered where a station is near enough to stand for the place, and withheld where none is.

GeoNames

Licence : CC BY 4.0 (texte de la licence)

Place names, coordinates and time zones for the almanac pages are from the GeoNames geographical database, licensed under CC BY 4.0.
