Resignation date simulator

Move a date and see how the day counts change.

2028 holiday dates use KASI provisional calendar data before the official almanac. Calculations are estimates and may change with the official announcement or holiday changes.

Dates to compare

“Resignation date” means your last day of employment, which may differ from your last working day.

This date is included in the remaining-day counts.

Whole days only. Leave is placed backward from the last scheduled workday.

Your inputs are not saved or sent.

Results assume a five-day workweek and are estimates for reference, not legal advice.

Frequently asked questions

How do I use the simulator?
Enter an employment start date, calculation date and two candidate last employment dates. Start the comparison, then adjust the second date by hand or with the day buttons.
Does moving to a weekend add a workday?
It can add calendar days but not scheduled workdays. The result makes no judgment about which date is better.
