The word “a day” (yewm) is used 365 times in the Quran. The figure
365 does not only represent the number of days in the calendar, but
it is also the figure that shows the astronomical relationship between
our world and the sun. When our world completes its turn around the
sun, it has revolved 365 times around its own axis. In other words,
when the world has completed its cycle around the sun, this means we
have lived 365 days on earth. It is important that the word “a day” is
used 365 times in the Quran, because the world’s revolution around
the sun takes 365 days.
The different uses of the word “day” in the Quran is phenomenal.
While the singular word “a day” is used 365 times, its plural (eyyam,
yewmeyn) is used 30 times. This represents the number of the days in
a month, which is 30. So it is meaningful that while the singular “day”
(yewm) is mentioned 365 times, the plural of it (eyyam, yewmeyn) is
mentioned 30 times.
In the solar calendar, the months have either 30 or 31 days and in
the lunar calendar the months have either 29 or 30 days. So, the number 30 is the intersection group for both calendars. In the community to which the Quran was revealed, the lunar calendar was in use; the
mention of “30” is therefore meaningful. It takes 29.53 days for the
moon, the satellite in the sky, to make a month. The rounded figure
is 30. With such mathematical miracles, we witness that the Quran
calculates correctly this rounding up business. Likewise, the world
completes its cycle around the sun in 365.25 days exactly. The rounded figure is 365.
