How it counts
- By default it is end date − start date. January 1 to January 2 is 1 day.
- Turn on “Count both start and end dates” to add a day, for example when counting trip days (Jan 1–3 = 3 days).
- The calendar figure counts a month when the same date comes around. January 31 to March 1 is 1 month and 1 day.
- Weekdays only remove Saturdays and Sundays. Public holidays are not removed.
Legal periods in Korea
Contracts and laws usually exclude the first day. Article 157 of the Korean Civil Act says the first day of a period in days, weeks, months or years is not counted, unless the period starts at midnight. A contract’s own rule comes first.
FAQ
What date is 7 days from today?
Use the D-day Counter’s “Nth day” mode with “Count the start date as day 1” turned off, and enter 7.
How do I get business days?
Take the weekday count and subtract the public holidays in that period. This tool does not remove holidays.
Why don’t months match the day count?
Months have 28 to 31 days, so a month is counted when the same date comes around again.
