Good morning!  I'm Kerry J Harrison co-author of "Untapped Wealth Discovered."
I can bet you anything that if I were to ask you which month of the year you think would be the best to take your vacation most of you probably point to any of the three summer months.  That is, from June to August.  Some may say December and others may say March.  Those looking for winter get always may choose a month from December to February.  Those with kids may choose March because of the spring break.  While others would choose any of the summer months for obvious reasons.
According to recent results published by a CNN survey it was revealed that July came out on top for the following reasons:  July is one of the slowest months in most workplaces.  July is the month when many garment and clothing companies actually close their doors because of slower activity in the garment industry.  It is also a very slow time for lawyers and medical specialists because may of their patients would rather not have surgery during the month of July. 
July is also smack in the middle of summer and it's the month that most parents would choose to take their kids on vacation.  According to our watchers in Europe it's the time when most choose to travel across Europe because of the fine weather.
When it comes to one of the worst months for vacation time December wins hands down and this is so mainly because of the busy holiday season.  It's the time that if one does choose to take their vacation they have to ensure that they leave a backup in place, tell the boss way ahead of time that they want to take their vacation in December so that the boss can make arrangements to back fill, and it's the month that is probably the shortest work months because of the statutory holidays.
Finally, take note of April.  It's the time when most people feel the most pressure because of income tax season.  Persons feel pressured because they know that their tax returns are due, and most accountants view April as a month from hell because they are almost always under the gun to complete tax returns.
