Template:Datetime format matching

Alpha tokens	For alphabetic tokens (for example, Month), a strict match requires the input value to be the correct case. For example, the MON token is strictly matched by JAN but not by Jan, and the reverse is true for the Mon token. For non-strict matching, the alphabetic tokens are matched by any combination of uppercase and lowercase input.
HH, MM, DD	For these tokens, a strict match requires a leading zero for values less than 10. For non-strict matching, a value less than 10 can also be represented by a leading blank followed by a single numeric digit.
BH, BM, BD	For these tokens, a strict match requires a leading blank for values less than 10. For non-strict matching, a value less than 10 can also be represented by a leading zero followed by a numeric digit.
DAY	For this token, a strict match requires a single digit for values less than 10. For non-strict matching, a value less than 10 can also be represented by a leading zero followed by a numeric digit.
ZYY	For this token, a strict match requires two digits for values less than 100. For non-strict matching, a value less than 100 can also be represented by a leading zero followed by a two numeric digits.
