2250  hemera  hay-mer'-ah

 feminine (with 5610 implied) 
of a derivative of hemai (to 
sit; akin to the base of 
1476) meaning tame, i.e. 
gentle; day, i.e. (literally) 
the time space between dawn 
and dark, or the whole 24 
hours (but several days were 
usually reckoned by the Jews 
as inclusive of the parts of 
both extremes); figuratively, 
a period (always defined more 
or less clearly by the 
context):--age, + alway, 
(mid-)day (by day, (-ly)), + 
for ever, judgment, (day) 
time, while, years.
