Resignation & Paid Leave Scheduler | Calculate Your Last Office Day in Japan

Enter your target resignation date (or the date you want to start using your remaining paid leave) and this tool calculates your last office day, the day your leave consumption starts, and your resignation date — following Japanese employment norms. It also shows the statutory 2-week notice rule and a typical company-notice-period reference. Everything runs in your browser; nothing is sent to a server. This is not legal advice.

Calculation direction

The dates and leave days you enter are processed entirely in your browser and are never sent to a server.

This tool provides a general estimate for informational purposes only and is not legal advice. Always confirm your actual resignation process with your employer's HR department and work rules (shugyo kisoku).

Fill in the fields above and press "Calculate".

How to use

  1. Choose a calculation direction (work backward from a target resignation date, or forward from a leave start date) and enter the corresponding date. If you're unsure how many paid-leave days you have left, check first with the Paid Leave Accrual Calculator.
  2. Enter your company's typical notice period (defaults to 1 month) and the date you plan to submit your resignation notice.
  3. Press "Calculate" to see your last office day, leave start date, and resignation date, along with statutory and company-rule notice-period references.

How it works

How paid-leave consumption is counted

Paid leave (yukyu) is taken against days you would otherwise be scheduled to work. Weekends and public holidays are not workdays to begin with, so they are not counted against your leave balance. This tool counts leave consumption using scheduled workdays only — excluding Saturdays, Sundays, and Japan's official public holidays (including substitute holidays), using the same holiday dataset as the Business Day Calculator on this site.

How the dates are calculated

  • Backward (from a target resignation date): counting the resignation date as day one, the tool steps back through scheduled workdays until your full leave balance is accounted for — that date becomes your leave start date. Your last office day is the scheduled workday immediately before that.
  • Forward (from a leave start date): counting that date as day one, the tool steps forward through scheduled workdays until your leave balance is used up — that date becomes your resignation date.

About the notice-period references

  • Statutory reference: under Civil Code Article 627, an employment contract with no fixed term ends 2 weeks (calendar days) after notice is given — the legal minimum. This tool uses the common simplified rule of "notice date + 14 days" used by most reference sources, rather than the strict day-counting rule in Civil Code Article 140.
  • Company-rule reference: calculated by subtracting your selected notice period (2 weeks/1/2/3 months) from the resignation date. Actual requirements vary by employer — always confirm with your actual work rules.

Data coverage

Holiday data covers 1955–2027. Dates outside this range return an error rather than a guessed answer.

Disclaimer

This tool provides a general estimate for informational purposes only and is not legal or HR advice. Always confirm your actual resignation process and timeline with your employer's HR department, your work rules, or a qualified professional (e.g. a labor and social security attorney / "shakai hoken romushi").

FAQ

Are the dates or numbers I enter sent anywhere?

No. All calculation happens locally in your browser; nothing is transmitted to any server.

Is this legal advice?

No. This tool provides a general estimate for informational purposes only, not individualized legal or HR advice. For your actual resignation, please confirm the process with your employer's work rules or consult a qualified professional.

The law says I can quit with 2 weeks' notice — why would I follow my company's longer notice period?

Civil Code Article 627's 2-week rule is the legal minimum, and it is legally sufficient. However, most Japanese employers' work rules require longer notice (often 1 month), and in practice employees generally follow the company rule to allow for a smooth handover and avoid friction. This tool shows both references so you can weigh them for your own decision.

How are weekends and holidays during my leave period handled?

Paid leave is only taken against days you'd otherwise be scheduled to work, so weekends and public holidays within your leave period don't count against your leave balance. This tool lists exactly which days those are.

I have a large leave balance (30–40 days) — how long should I plan for?

The more leave days you have remaining, the longer the consumption period will take. As a rough guideline, many employees set their last office day 1–2 months before their resignation date when they have a large balance. Enter your actual remaining days into this tool to see the specific dates for your situation.
