Calendar weeks 2033: quarters, holidays and planning periods

Austrian week planning should combine the ISO number with the selected federal state. That makes province-specific holidays, semester-break groups and national dates comparable before a team reserves leave or a family books travel.

This overview follows the usual Monday-to-Sunday week structure and lets you filter by year, federal state 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.

After choosing the federal state, use the holiday planner to test adjacent working days. Open the school holiday overview when BMB break groups control childcare or travel; subscribe or export only after that scope is settled.

FAQ

Common questions about calendar weeks

Short answers about week numbers, federal states 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 Austria, week-based planning usually starts on Monday.

Why filter by federal state?

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

When should I use the holiday planner instead?

Choose the Austrian federal state first. Calendar weeks define the window; the planner then tests which adjacent working days create a useful Fenstertag block.

How do calendar weeks help in planning Fenstertage?

By displaying public holidays and school vacations alongside week numbers, you can easily identify weeks that contain holidays (like Ascension in KW 20 or Corpus Christi in KW 22). This allows you to plan your Fenstertage (bridge days) and book your vacation early.

Data basis

Calendar data with official source anchors

ISO week numbers come from the selected year. RIS holiday rules and BMB school dates determine which Austrian federal-state markers appear.
