[수학 이야기 #23] 13일의 금요일은 과연 특별한 날일까?
(이미지 출처 CC0 license) 13일의 금요일은 특별한가? 그레고리력의 주기 그레고리력의 규칙을 다시한번 살펴보자. 평년은 365일로 한다. 4의 배수인 해는 원칙적으로 윤년 (366일) 100의 배수인 해는 윤년에서 제외 400의 배수이면 예외적으로 윤년에 포함시킴. 따라서 그레고리력은 음력과 관련된 설날, 추석, 24절기 등을 제외하면, 순전히 태양력만을

[수학 이야기 #22] 날짜를 알면 요일을 알 수 있다?!
(이미지 출처, CC0 license) 날짜와 요일의 관계 율리우스력에서 그레고리력으로의 전환 율리우스 카이사르가 도입한 율리우스력은 다음과 같은 규칙으로 날짜를 계산하였다. 평년은 일 이고, 4년마다 윤년 (366일)을 배치한다. 이는 굉장히 부정확한 날짜 계산법이었는데, 그 이유는 지구가 태양을 한 바퀴 돌아 제자리로 올 때까지 걸리는 시간이 약 일 이기
