your prefered date format?
TIL via Wikipedia that how date is represented can be describe with 'endianness':
Order of the basic components:
B – big-endian (year, month, day), e.g. 2021-03-31 or 2021.03.31 or 2021/03/31 or 2021 March 31
L – little-endian (day, month, year), e.g. 31.03.2021 or 31-03-2021 or 31/03/2021 or 31 March 2021
M – middle-endian (month, day, year), e.g. 03/31/2021 or March 31, 2021
@luka Can I be a pain, and say that I prefer ISO 8601's YYYY-MM-DD?
@luka I voted YYMMDD but like some sensible people here would prefer YYYY-MM-DD.
It's logical, simple, sorts well, is the standard format for not insignificant proportion of the world's population and it's unambiguous given that YYYY-DD-MM is not in widespread use (and a swift boot to the crotch for anybody stupid enough to use that, please).
@luka The Julian date (JD) of any instant is the Julian day number plus the fraction of a day since the preceding noon in Universal Time. Julian dates are expressed as a Julian day number with a decimal fraction added. For example, the Julian Date for 00:30:00.0 UT January 1, 2013, is 2 456 293.520 833.
I've been using this more and more. 1 unit = 1 day with the day unit cycling at noon UTC. The epoch is the start of the Indiction, Solar, and Lunar cycles, which aligns to November 24, 4714 BC in the Gregorian calendar. It's most notably currently used in astronomy. It sorts well and time intervals are easy to calculate. It's already a single value that gives both date and time.
@luka YYYYMMDD, of which YYMMDD is a close enough approximation if you're not dealing with historical data, I'd say.
@luka For what usecase ? for reading as a human ? DDMMYY. For filename/log/cell/data/anything that could be ordered? then something more ISO such as YYMMDD
@luka I voted, but my answer would have been different if the year were represented by four digits instead of two or if the month had been represented by letters instead of numbers.
@luka I selected YYMMDD, but really it's YYYYMMDD or YYYY-MM-DD ... a lot of the dates I deal with are in the 20th century, and it matters.
I'm old and don't want to confuse myself with century changes, even though I don't really expect to see the next one.
This format, especially when used on file names, makes much of my work easier to do.
