Formula & Theory - Palindrome Date Finder
The scanner iterates day-by-day from start to end, validates each date against the calendar (including leap years), formats it with two-digit month and day, then checks the resulting 8-character string against its reverse:
str = format(year, month, day, chosenFormat) // 8-character string
isPalindrome = str == reverse(str)Calendar validity uses the standard rule:
isLeap(y) = (y % 4 == 0 and y % 100 != 0) or (y % 400 == 0)
daysInMonth[2] = 29 if isLeap(y) else 28The “days from today” column is a signed difference between the matched date and today in UTC days.
