Date and time notation in Iran

In Iran, short dates are written in "year/month/day" from; for example: 1992/10/16

۱۳۸۹/۵/۱۶

Long dates start with day, followed by month and ended with year (although one should bear in mind that Persian is read from right to left). For example:

۱۶ مرداد ۱۳۸۹

Both two-digit and four-digit years are valid but months and days are not usually padded with leading zeros.
