	<string name="second">"second"</string>
	<string name="seconds">"seconds"</string>
	<string name="minute">"minute"</string>
	<string name="minutes">"minutes"</string>
	<string name="hour">"hour"</string>
	<string name="day">"day"</string>
	<string name="days">"days"</string>
	<string name="week">"week"</string>
	<string name="weeks">"weeks"</string>
	<string name="month">"month"</string>
	<string name="months">"months"</string>
	<string name="year">"year"</string>
	<string name="years">"years"</string>

These strings should be handled like the other plurals but also with an argument (%d day, %d days).

The reason for it is that the placement of the variable is different in Hebrew (Single day is usually not counted, 2 days is a single word, starting from 3 days there's a number before the plural form of the expression "day" in Hebrew).

In Arabic it's much more complicated but based on the same principals.

EDIT: Also, there's an option to use CLDR instead of asking the translators to translate the days of the week, etc.
