When it comes to selecting a date to move into a property, not only is the year of birth of the main occupants taken into account, so is the direction in which the property lies. For instance, if your property faces north, it is represented by the horse and you should not move on a day of the rat (the next two being Thursday and January 26), as that creature clashes with the sitting direction of your property. Some fung shui masters will also advise against an individual sleeping with his head pointing towards, or working at a desk with their back against, the direction that clashes with their year of birth. Having a property facing your 'clashing' direction is not an issue, however. Although personal clashes are used in calculations involving date selection it is important to note that there are several factors to consider. A couple born in the years of the snake and the pig, for instance, are not necessarily destined for divorce. Animals and elements representing the days, months and hours of birth should also be analysed before the compatibility of a couple is determined and, when it comes to interpersonal relationships, a skilled astrologer will identify all troublesome elements and take a nuanced view of how they interact with a partner's chart.
