Up to now, the standard practice for categories for sailings of ships carrying immigrants is to name them in the format:
[[Shipname, sailed Month day, year]]
for example, the guide to categories for emigrant-immigrant ships points to:
[[Category:SS_Polynesian,_sailed_April_20,_1882]]
To be honest, I've never been entirely comfortable with that standard, because while it is the usual American usage, it is not the standard usage in most countries of the world. (If you want to learn more about that, Wikipedia has a handy chart that explains, among other things, that that particular date format is only the fourth most commonly used system in the world.) And, since we are at least trying to build a global family tree, rather than an American family tree, it seemed to me that it would behoove us to use a system which isn't quite so strongly identified with one particular place. (On the other hand, that could just be because I'm Canadian, since Canada is the only country in the world which steadfastly refuses to make up its mind, and thus uses three different date orders. [Or at least, so says Wikipedia.])
However, the Month, Day, Year format was well entrenched before I joined WikiTree, and changing it seemed to be too much like work.
Now, Malcolm has pointed out in another thread that the date format:
YYYY-MM-DD
is an ISO standard. (Specifically, ISO 8601, if you're interested.)
This system makes a lot of sense for a number of reasons:
- It's an international standard, so adopting it would not be a matter of favouring one country's habits over another, but rather accepting an already recognised standard.
- Unlike those formats which put the year last, which can be unclear as to which part is the month and which part is the day (at least up until the 13th of each month), it's unambiguous.
- Switching to this format would make the sailings by a particular ship automatically sort into chronological order.
On the other hand, switching would still entail a lot of work.
