Why does one day change your resignation date?
How this is calculated
Severance pay requires one full year of continuous service. Fall even a day short and you get nothing. Paid leave works differently — under one year of service you earn 1 day per month of perfect attendance (up to 11 days); once you pass one year, you get 15 days all at once, then one more day every two years, up to 25. This tool takes just your start date, calculates both dates separately, and tells you the earliest date that captures both.
Who this is for
Anyone who already has their next move lined up and is deciding when to hand in notice, anyone weighing leaving right before hitting their one-year mark, or anyone curious how much they'd lose by leaving with unused paid leave.
What this doesn't do
It can't account for employer policies that are more generous than the legal minimum (extra leave days, fiscal-year settlement, etc.). The estimated severance figure is also an approximation based on take-home pay and will differ from the real number — actual severance is calculated from your average wage over the prior 3 months, including bonuses and allowances. The accrual date for employees who started at the end of a month is a point where practice varies, so we'd recommend confirming with a labor attorney (노무사) if it matters for you.
