What this result means
The calculator counts the entry date as day 1. It does not determine how many days Korea has granted you and cannot account for extensions or special immigration instructions.
How to use it
- Copy the permitted-day count from your official visa or immigration record.
- If an official document gives a specific expiry date, use that date rather than a calculated estimate.

Frequently asked questions
Does arrival day count as day 1?
This calculator uses arrival day as day 1 and clearly shows that assumption.
Can this tool tell me how long my visa allows?
No. You must supply the permitted days from an official record.
Does this confirm my legal stay expiry?
No. Immigration records and instructions are authoritative and may differ from simple date math.
