In particular,
- Date X + 12 Months
- Date X + 1 Year
- Date X + 365 days
Will these result in all same dates at any point of X?
In particular,
Will these result in all same dates at any point of X?
It will not, the third example might be different from the other two because of leap years. A leap year have 366 days, so if between date X and date X + 1year there is a leap day, date X + 365 will result in one day less than date X + 1year
Also, it's important to state that this question is not a really good one, as stated by José Carlos Santos in the comments of this answer, and you should improve it, as to make this comunity more organized, and a better place for people who enjoy math and want to learn more.
