Day Periods for am-ET (Amharic for Ethiopia)

Reported by: ehoogerbeets@… Owned by: anybody
Component: other-supplemental Data Locale: am-ET
Phase: dsub Review:
Weeks: Data Xpath:



We should add day periods for Amharic for Ethiopia. They use a 12-hour clock there, but the day starts at the equivalent of 06:00am Gregorian time. That is, 12:00 morning Ethiopic = 06:00am Gregorian, and 6:00noon Ethiopic = 12:00pm Gregorian, etc.

The day periods are pretty consistent throughout the year because Ethiopia is right near the equator, so the day length does not vary very much.

Here are the periods:

ጠዋት - morning - 12:00 to 5:59 Ethiopic = 06:00 to 11:59 Gregorian
ቀትር - noon - 6:00 Ethiopic = 12:00 Gregorian (one minute long!)
ከሰዓት - afternoon - 6:01 to 11:59 Ethiopic = 12:01 to 17:59 Gregorian
ከምሽቱ - evening - 12:00 to 5:59 Ethiopic = 18:00 to 23:59 Gregorian
ከሌሊቱ - night - 6:00 to 11:59 Ethiopic = 00:00 to 06:00 Gregorian

These day periods are only used with the Ethiopic calendar dates and times. When giving times in Gregorian, you use the regular AM/PM meridiems, translated to Amharic:

ጠዋት - AM
ከሰዓት - PM

As for the time of day corrections, see ICU ticket http://bugs.icu-project.org/trac/ticket/11675

Can we have a new ticket for the time offset issue?

I am not sure that this is limited to day periods. Taking 5am Gregorian and printing 11night Ethiopic is one step, but what about the date? Is Wednesday 5am Gregorian equivalent to Tuesday 11night Ethiopic?

Will it break existing usage if the time of day shifts with the calendar? Should there be a separate calendar type, or an additional setting/keyword, for selecting this behavior?

From what I understood, I think it would be Tuesday, yes, because the day changes at 6am instead of midnight. We shouldn't take my word for it though. We should verify with an actual native to make sure.

The Ethiopic calendar always has this associated time shift with it, so I don't think we need a separate calendar type for it.

Also, from what I understood certain other cultures in the region also use this shifted time representation (sw-TZ and sw-KE for example), though I am not sure what calendar they use. This wikipedia article suggests that the calendar and time representation goes with the language you are speaking: http://en.wikipedia.org/wiki/Date_and_time_notation_in_Africa

This would require that these day periods be associated only with an Ethiopic calendar, AND that we specify that it that starts the day with a 6 hour offset.

FWIW: The colloquial reckoning (Ethiopia and Eritrea) is that the day change occurs at 1 in the morning (what would be 7AM by western conventions). I haven't come into a government document to support this. The following article is supportive of this view:
