You don’t need to put dates down and by law they can’t actually ask you that question because it can be used to calculate your age. This is covered by the new age discrimination legislation that came into effect in October 2007. Similarly they can’t ask you for your date of birth. In reality, a lot of people interviewing you are going to be poorly informed and will most likely ask you anyway. You can decline to answer and explain the law to them, but it would most likely look suspicious and be antagonistic. If you feel the same way then the best way to handle this is to leave out the specific months were you joined and left employment and just use the year. If your career break was between years and they ask what you did, just say you took a break, you went travelling, you stayed home with your family etc.
