These references apply only to people with the relevant comprehensive permission: 28h/week during normal school periods and 8h/day during an official school-designated long vacation. Hours across all jobs are combined. This tool does not determine your status or individual permission conditions. Official source · Checked 2026-08-19

Combine every part-time job

A total from one employer does not show your complete schedule. Enter each job separately and BaitoPlan combines the hours before showing your status.

  • Monday-to-Sunday weekly history
  • All jobs combined
  • Separate normal and official-vacation modes

Two periods, two different checks

During a normal school period, the configured general reference is 28 hours per week. During an official long vacation designated by your school, enter shifts by day and compare the combined daily total with 8 hours. The calculator does not treat 40 hours as a universal weekly limit.

FAQ

Common questions

Do hours from two jobs count together?

BaitoPlan combines every job you enter. Check your individual permission and official guidance for the conditions that apply to you.

Is 28 hours automatically allowed for every student?

No. This reference is relevant only when your status and individual permission include that condition.

How are long-vacation hours checked?

Use daily entry. The calculator combines all jobs for each day and compares the total with the configured 8-hour daily reference.

BaitoPlan provides estimates and general information. Results depend on what you enter and are not legal, immigration, tax, or financial advice.
