Birthday Note

April 10, 2008 or October 4, 2008

It would be better if the digits were in a normal date order. Given its condition, I think you have a spender.

According to wikipedia, a common sequence in the vast majority of the world's countries is DAY/MONTH/YEAR. YEAR/MONTH/DAY is apparently the standard in Asian countries, Hungary, Sweden and the US armed forces. And finally, MONTH/DAY/YEAR is used primarily in the United States, partially in Canada, and a few other countries.

For modern notes with 7 digit serials issued in countries using the gregorian calendar, the day has to be one digit and the month has to be 2 digits or vice versa because year is four digits to amount to 7 digits(it could not be otherwise in a 7 digit serial, because if year had only 2 digits, which is the only other possibility, 5 digits would be needed to cover both day and month which is impossible).

Also, IMO either day or year shouldn't start with a zero because it would make it quite unusual. They both have to amount to a total of 3 digits. So, for example, if day is the 6th, month is February and year is 2008, it would be odd to only have one of the two have a zero in the beginning, like 6022008 or 0622008.
