How this Boulogne-Billancourt calendar is made
The year is 2027; dates are local to Boulogne-Billancourt (Europe/Paris). The weekend column follows the weekend days for France in python-holidays (Sat, Sun).
Public holidays: the OpenHolidays API (ODbL 1.0). A regional holiday is shown when it applies in Île-de-France, matched by the ISO 3166-2 codes of the areas containing Boulogne-Billancourt on Wikidata; holidays of other regions are only in the JSON file. A date marked "estimated" depends on the moon or an official announcement.
School holidays: OpenHolidays API (ODbL 1.0), every period that touches 2027. The source has published school holidays for Île-de-France up to 3 July 2027; later dates are marked "not published yet" — not the same as no school holidays.
Sunrise and sunset are calculated from the coordinates with the NOAA solar equations (the sun's upper edge on a sea-level horizon, standard refraction), in local time; approximate to a few minutes, with no allowance for terrain or buildings.
Typical high and low are interpolated day by day between the 1991–2020 monthly averages (each placed at the middle of its month) — a typical value, never a forecast. A comfortable month means average daytime high between 18 °C and 29 °C and under 80 mm of rain in the month. Averages for 1991–2020 over the surrounding area, a grid square about 50 km across, so a coast or a nearby mountain can make the town itself warmer or cooler.

This calendar covers the 1,500 destinations with the most places to stay in this guide (chain properties plus hotels recorded in Wikidata) that have climate data and a time zone. It has no prices, availability, occupancy, demand or crowd levels: the guide has no such data, and nothing here estimates them.
