Author Topic: Logging Date Format: DDMMYR?  (Read 2160 times)

I notice that most DX cards I receive the date format is DD-MM-YR.  I use HRD for logging, the computer cofigures the format to automatically be in MM-DD-YR here in the US.  I upload my logs to LOTW and to eQSL.  So, if my uploaded files are in US regional format, wouldn't that mean that electronic cards might not find a match date wise, and would result in no confirmation?

That is very possible.

Most common accepted format I have seen for years is either DD-MMM-YY, where MMM is 3 letter month abbreviation or DD-MM-YY, all numerics. Trying to avoid anything US-centric for dates, such as the standard US format of MM-DD-YY, should make your QSLing life easier.  I have used the DD-MMM-YY format for years and it has become second nature for me when doing QSL cards to do it that way.

Agree. 08-NOV-2011 is the format I use on cards (and, of course, UTC for time). You'll also find some stations abbreviate the month using Roman numerals.

There should not be a problem with LOTW matches. The ADIF standard for DATE should assure this.

8 Digits representing a UTC date in YYYYMMDD format.

I just ordered some new QSL cards (my first reorder in 20 years) and I changed the format to agree with the rest of the world.  Day, Month, Year.  I still keep my logbook using US format, however.

One more vote for DD MMM YYYY; my log (an MS-Access database) stores the date in its own mysterious way but I can have it formatted any way I like on the way back out to LOTW and QSL cards.   The formatting string I use for most things includes "UTC" before the time, and looks like this:  "UTC "hhnn  dd mmm yyyy

I actually thought using arabic numerals for the day and roman numerals for the month was pretty sensible, but with the rise of computer logging, I haven't seen that format in use in a long time.

Totally confusing. How will we ever know which "11" is the year and which is the day or the month???  Huh

Web developers have been frustrated with this difference for a while.

The W3C says:

"Visitors to a web site from varying locales may be confused by date formats. The format MM/DD/YY is unique to the United States.
Most of Europe uses DD/MM/YY.
Japan uses YY/MM/DD.
The separators may be slashes, dashes or periods. Some locales print leading zeroes, others suppress them. If a native Japanese speaker is reading a US English web page from a web site in Germany that contains the date 03/04/02 how do they interpret it?"

For the life of me I could never understand why the USA decided to use MM/DD/YY !!  It's so counter intuitive.
Why then did they not follow the same logic and use the time format 45:12PM ?

It might have been because mail was very slow way back when we became a country?
