## Limitations

Croatia 2026 article 1 general holidays over an explicitly selected Monday-Friday planning baseline. Article 2 memorial days do not add rest. Article 3 religious rights depend on the person and, for specified festivals, the chosen day; they are not included in a universal union. Individual shifts, replacement weekly rest, employer/local/sector/school/bank schedules, payroll, legal deadlines and future years are not computed. Apply 14 general holiday dates and retain 12 memorials separately. No extra Monday, personal religious leave, employer shifts or payroll are inferred. All values are computed from the formula above; no measurement or live data is involved.

## FAQ

**Is Monday-Friday mandatory for everyone?**

No. Choose mon_fri_planning explicitly. Legal weekly rest and individual shifts may differ; replacement rest and personal attendance are not inferred.

**Do memorial days or weekend holidays create an extra Monday off?**

Article 2 memorials do not add general rest. Article 4 prohibits next-day transfer when the date is Sunday, a holiday or a non-working day. No unpublished substitute is inferred.

**What about religious holiday rights?**

Article 3 protects specified religious groups; some festival days are individually selected. This article 1 general calendar does not combine them into national holidays or infer a person's religion.
