Calendar weeks 2015: quarters, holidays and planning periods

Calendar weeks are the practical layer between a daily calendar and quarterly planning. They make recurring work easier to compare: project milestones, booking windows, payroll cycles, school terms, public holidays and vacation planning all become clearer when the week number is visible next to the date.

This overview follows the usual Monday-to-Sunday week structure and lets you filter by year, canton and quarter. Public holidays, religious days, regional holidays, school holidays, weekends and today are highlighted so you can spot interruptions before they affect schedules or travel plans.

Use the holiday planner when you want to turn calendar weeks into concrete vacation days. Use the school holiday overview when school calendars are the deciding factor. For recurring coordination, keep the selected context reusable with calendar subscription or export.

FAQ

Common questions about calendar weeks

Short answers about week numbers, cantons and holiday planning.

What is a calendar week?

A calendar week groups seven consecutive days and is commonly used for project planning, scheduling and business communication. In Switzerland, week-based planning usually starts on Monday.

Why filter by canton?

Regional holidays and school holidays can differ by canton. Filtering makes the week overview more precise for regional planning.

When should I use the holiday planner instead?

Use calendar weeks for overview and coordination. Use the holiday planner when you want to select concrete vacation days and compare long weekends.

How do calendar weeks help with leave planning?

By displaying public holidays and school holidays alongside week numbers, you can quickly see which weeks contain holidays such as Ascension Day, Corpus Christi or Swiss National Day. That makes leave blocks and canton-specific days off easier to compare.
