מתי חודש נגמר:
עקרונית, יש כמה דרכים לחשב מתי חודש נגמר:
1. Thirty days has September, April, June and November, All the rest have thirty one, Excepting February, fun! And that has twenty eight days clear, And twenty nine in a Leap Year! 2. Thirty days has September, April, June and November. All the rest have 31 except February which has 4 and 24, 'til Leap Year gives it one day more. 3. Thirty days hath September, April, June, and November; all the rest have thirty-one, except for February alone. February has twenty-eight days clear, and twenty-nine in each Leap Year. 4. Thirty days hath September, April, June, and November; February has twenty-eight alone, All the rest have thirty-one, Excepting Leap-Year, that's the time When February's days are twenty-nine. 5. Thirty days hath Juvember, Apples, Noon and No Wonder, All the rest have Peanut Butter, Except my Grandma And she has a little red tricycle.
מתי יש שענה מעוברת?Leap year כדברי החמשירים? כשהשנה מתחלקת ב400 - כן. כשהשנה מתחלקת ב100, אך לא ב400 - לא. כשהשנה מתחלקת ב4, אך לא ב100(למעט המקרה של ה400) - כן.
