Car sales in the Saudi market touched 570,000 in 2013, registering an increase of 10 percent over the previous year, and the sales growth trend is likely to continue in 2014 too.
There is about a seven-day interval between springs and neaps. 1  Spring tide: Sun and Moon on the same side (0Â°) 2  Neap tide: Sun and Moon at 90Â°. 3  Spring tide: Sun and Moon at opposite sides (180Â°) 4  Neap tide: Sun and Moon at 270Â°. 5  Spring tide: Sun and Moon at the same side (cycle restarts)
Neap tides occur at about the same interval after the first or last quarters of the Moon. The time interval between successive spring and neap tides is variable, but for practical purposes it can be taken as being about 7 1/2 days (i.e. about one quarter of the average lunar month of 29.5 days)
