The DAY FILED is the day of the month on which the message was originated and must be used on all messages. (If TIME FILED is used, the date and time must agree). The day is written in figures only, no leading zeroes. No other punctuation, symbol or otherwise, is permitted. On voice, two digit days are spoken as two separate digits ("one seven" rather than "seventeen", etc.). The month/day is assumed to be UTC unless marked otherwise by a Time-Filed with another time zone designator shown. Example: 0215Z JUL 13, 2215EDT JUL 12, or 2215L JUL 12 (all three filing times/dates are equivalent). Groups such as "7/13" and other variations are not used. The year is not ever included - messages are typically delivered within 48 hours, hence month/day entries are sufficient to mark the end-of-year boundary.
