Calendar weeks 2029: quarters, holidays and planning periods

For German teams, the useful unit is the ISO week plus federal-state scope. Payroll deadlines, state holidays and staggered KMK breaks can then be compared without treating a regional interruption as nationwide.

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.

Use the holiday planner after selecting the federal state to compare leave around its holidays. Use the school holiday overview for KMK ranges, then preserve the agreed state and week in the subscription or export.

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 Germany, 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?

Set the German federal state before comparing leave. The week view locates the period; the planner checks whether state holidays make the surrounding working days useful.

How do calendar weeks help in planning bridge days?

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 German Unity Day. That makes bridge days easier to compare before you request vacation.

Data basis

Calendar data with official source anchors

ISO week numbers come from the selected year. State holiday scope and the KMK calendar decide which German federal-state interruptions are shown.
