Calendar knowledge
Using worldwide calendars for 2027 correctly
A focused twelve-month overview
The country calendar combines a compact month grid with ISO week numbers and the available nationwide and regional public holidays. School holidays, all ISO-week ranges, daily solar times and primary Moon phases have separate annual pages, linked directly from the country view.
Country and year remain the two central selections. Every calendar uses the localized country name and a stable URL, making it easy to bookmark or share a specific year. German and English versions point to one another with language alternatives.
National, regional and local dates
A holiday shown in a country calendar does not always apply throughout the country. Federal states, cantons, autonomous communities and municipalities may have their own rules. Regional dates are therefore marked with their stored scope instead of being presented as universally valid.
School holidays are a separate category. They follow education authorities and often vary by region or school group. Published dates are displayed only when coverage exists; a missing future period is clearly identified rather than filled with an estimate.
Planning with weeks, Sun and Moon
The dedicated ISO-week calendar lists every Monday-to-Sunday range. The solar calendar shows daily values for a named reference location, while the Moon calendar lists global primary phase instants in UTC. Convert those instants to your local time zone when planning.
Separating these topics keeps each page easier to scan and gives every dataset the explanation it needs. Official authorities remain decisive for legal deadlines, school attendance and statutory holiday status.
