Dates: Tarehe Gani?
36 DAYS OF THE WEEK.
Their names are based on the Moslem week, beginning after Friday, the holy day:

Jumamosi
the first day
Saturday

Jumapili
the second day
Sunday

Jumatatu
the third day
Monday

Jumanne
the fourth day
Tuesday

Jumatano
the fifth day
Wednesday

Alhamisi
the fifth day
Thursday

Ijumaa
the day of assembly
Friday

Note these points:
Jumamosi: mosi is an old form of the number one, rarely heard except in Jumamosi and telling dates (paragraph 38, below).
Alhamisi: the fifth day, which makes two fifth days. This name comes from an old reckoning that takes Sunday as the first day, thus Thursday is the fifth. Hamsa is an Arabic loan word for five.
Ijumaa: the day of assembly, or Lord's day; the Islamic holy day. Sometimes Christians will refer to Sunday as Siku ya Bwana, the Lord's Day.

TELLING THE YEAR
There is no short way of telling the year:
1984 is Mwaka elfu moja mia tisa themanini na nne
or also Mwaka elfu moja tisa mia themanini na nne
It is sometimes possible (when the century is not in doubt) simply to say: mwaka themanini na nne
