Japan Paid Leave Calculator | Statutory Grant Days & Remaining Balance

Calculate the statutory annual paid leave (yukyu) grant dates, granted days, and current remaining balance (accounting for the 2-year expiry) under Japan's Labor Standards Act Article 39, based on your hire date and employment category (full-time or part-time). Follows the official Ministry of Health, Labour and Welfare grant-day tables. Everything runs in your browser only — nothing is sent anywhere.

The dates, category, and days-taken you enter are processed only in your browser and are never sent anywhere.

Enter your hire date, the date to calculate as of, and your employment category, then press "Calculate" to see the result instantly.

How to use

Enter your hire date, the date you want to calculate as of (defaults to today), and your employment category (full-time, or the number of scheduled working days per week for part-time).
If you know how many days of paid leave you've already taken, enter them against the corresponding grant date (optional — defaults to 0 days).
Press "Calculate" to instantly see your grant history, most recent grant, current remaining balance (estimate), and next scheduled grant.

How it works

Basis for the grant-day tables

Under Article 39 of Japan's Labor Standards Act, an employee who has worked continuously for 6 months from their hire date and has attended at least 80% of scheduled working days is granted paid leave. After that, on each yearly anniversary of that first grant date, further days are granted as long as the 80%-attendance condition was met over the preceding year. (Source: Ministry of Health, Labour and Welfare, "Startup Roudou Jouken" Q&A on annual paid leave.)

General employees (full-time)

6 months: 10 days
1 year 6 months: 11 days
2 years 6 months: 12 days
3 years 6 months: 14 days
4 years 6 months: 16 days
5 years 6 months: 18 days
6 years 6 months or more: 20 days

Proportional grant (for part-time employees working under 30 hours/week AND 4 or fewer scheduled days/week, or 216 or fewer scheduled days/year)

4 days/week: 6mo 7 / 1y6mo 8 / 2y6mo 9 / 3y6mo 10 / 4y6mo 12 / 5y6mo 13 / 6y6mo+ 15
3 days/week: 6mo 5 / 1y6mo 6 / 2y6mo 6 / 3y6mo 8 / 4y6mo 9 / 5y6mo 10 / 6y6mo+ 11
2 days/week: 6mo 3 / 1y6mo 4 / 2y6mo 4 / 3y6mo 5 / 4y6mo 6 / 5y6mo 6 / 6y6mo+ 7
1 day/week: 6mo 1 / 1y6mo 2 / 2y6mo 2 / 3y6mo 2 / 4y6mo 3 / 5y6mo 3 / 6y6mo+ 3

If scheduled weekly working hours are 30 hours or more, the employee does not qualify for the proportional table even with 4 or fewer scheduled days per week — the general table applies instead. From 6 years 6 months onward, every category is capped at the value in the table's final column.

How the remaining balance (expiry / carryover) is calculated

The right to unused annual paid leave expires 2 years after the grant date, and carryover is allowed for one year only (Labor Standards Act Article 115). This tool calculates the remaining balance using only the two most recent grants that have occurred as of the as-of date — any grant older than that is treated as already expired and excluded. Days-taken entries are subtracted from their corresponding grant. There is no explicit legal rule for which grant should be consumed first when multiple are available; this tool assumes the older (carried-over) grant is consumed first, which is the more employee-favorable assumption and is disclosed on the page.

What this tool assumes

It assumes the 80%-attendance requirement was met at each grant date and does not verify attendance itself.
It does not support irregular scheduling patterns where working days are defined over a period other than a week.
Results are estimates only. Actual granted and remaining days can differ based on company work rules or individual employment contracts. For an authoritative determination, consult a certified labor and social security attorney (shakai hoken roumushi) or the equivalent professional.

FAQ

Is the hire date or days-taken information I enter sent anywhere?

No. All calculations happen entirely in your browser — no data is ever sent to a server.

Where does the grant-day table come from?

It's taken directly from the Ministry of Health, Labour and Welfare's official Q&A on annual paid leave, which sets out the statutory grant-day table under Article 39 of the Labor Standards Act — both the general (full-time) table and the proportional-grant table for part-time employees.

Who qualifies for the proportional grant?

Employees whose scheduled weekly working hours are under 30 hours AND whose scheduled working days are 4 or fewer per week (or 216 or fewer per year) qualify. If scheduled weekly hours are 30 or more, the employee is treated the same as a full-time employee under the general table, regardless of how few days they work.

By when do I need to use my paid leave before it expires?

Under Article 115 of the Labor Standards Act, the right to each grant of paid leave expires 2 years after it was granted. Since only one year of carryover is allowed, in practice you need to use each grant within the year it was given plus the following year.

Can I submit this result directly to my employer as an official record?

No — this is an estimate only. It does not verify the 80%-attendance requirement, and if your company's work rules are more generous than the statutory minimum, those rules take precedence. For an authoritative figure, check with whoever manages attendance records at your company, or consult a labor and social security attorney.
