공식

days=(start date + 6 months)−start date\text{days} = \text{(start date + 6 months)} - \text{start date}

Count the calendar days from the start date to the same date six months later. Month lengths differ (28–31 days), so the total depends on the months.

풀이 예제

Easy: January to July 2026

6 months from 1 January 2026 is 1 July 2026.

January 31 + February 28 + March 31 + April 30 + May 31 + June 30 = 181 days.

That is the shortest possible 6 months; in a leap year January–June has 182 days.

Medium: July to January

6 months from 1 July 2026 is 1 January 2027.

July 31 + August 31 + September 30 + October 31 + November 30 + December 31 = 184 days.

This is the longest possible 6 months: it includes July and August, which both have 31 days.

Hard: from 31 August, over a leap year

There is no 31 February, so 6 months from 31 August 2027 lands on the last day of February: 29 February 2028 (2028 is a leap year).

September 30 + October 31 + November 30 + December 31 + January 31 + February 29 = 182 days.

자주 하는 실수

  • Assuming 6 months is 180 days. That uses 30-day months; real months make it 181 to 184 days.
  • Forgetting leap years: any 6 months that include 29 February have one extra day.
  • Counting both the start and end dates. From 1 January to 1 July is 181 days; counting both ends gives 182.
  • Landing on a date that doesn’t exist: 6 months after 31 August is the end of February, not “31 February”.
