dates as per asme y14.100-2004
had anyone else not relaized that as per asme y14.100-2004 para 4.28, dates on drawings are to be written year-month- day rather than month-day-year? i have always written dates month-day-year, am i the only one?
eng-tips forums is member supported.
i use to write the date year-month-day but was told to change by management because it was not standard to everyday folks.
best regards,

never argue with an idiot. they'll bring you down to their level and beat you with experience every time.
yes, i have seen it. a lot of companies here in the usa refuse to follow it. we tried to follow it at my last company, no go.

okay, so what you are saying is that this is one of those rules that a bunch of people, who live in their own private worlds, sat down and thought "how should we do this?" and without consulting anyone in the real world, came up with a way to do something that is completly different from the way everyone else in the world does it everyday. and as such, everyone has tried to make this work at some point and everytime they have just gone back to doing it "wrong" because they couldn't change everyone else's minds in order to do it "right".
is that about how you all see it?
yes. the people that write the standards wouldn't have a job if they didn't get together to change something.

back in the uk it was day, month, year.  i believe this goes for all of europe, not sure about the rest of the world.
this could cause confusion when looking at us documents.
my guess is they chose year month day because no one else does it this way and it would help avoid confusion!
also if you have the date as part of the file name it sorts better this way.
maybe there is an iso convention they are trying to match.
we started using that format when the software we were using was storing it in that format. this way we could pull the date from the pdm system and use it directly to populate the drawing fields.

hmm.  i think the "year first" date format is/was/has always been a military requirement, at least for their internal reports (not sure it ever flowed down to the subcontractors, but i did see it on level 1 drawings if memory serves)?  thus its inclusion under the y14.100 "tree" of specifications, which is the ansi continuation of the old dod-std-100, which is the continuation of the predecessor mil-std-100.  which is why we (a civilian company with nothing much to do with mil/nav/af/nasa) call out y14.5 on our drawings, not y14.100...
year(4 digit)-month-day is the most logical way (imo) of writing a date. you wouldn't write time as min-sec-hour or sec-min-hour so why suddenly change the format (large to small) when writing a date.
cbl-
if only that was the way that americans as a whole wrote the date. i think it makes the most logical sense, but like anything else that is ingrained practically from birth, i can't see it changing any time soon.
some places use day-month-year. if you see 11-12-06, would you call it dec 11 or nov 12 if you didn't know the system?
