It is advisable to congratulate a person on his birthday on time.
However, if you were unable to present the gift to the hero of the occasion on the holiday, you can do it later.
If you believe the signs, then such an action is unlikely to lead to bad consequences.
But congratulating someone on their birthday in advance is definitely not a good idea.
What is the danger of early congratulations?
According to the signs, a “false start” associated with giving a gift and making wishes can provoke very serious problems.
It is believed that in this case the hero of the occasion's plans may be disrupted.
But this is not the most dangerous consequence. It is possible that the person who will celebrate his birthday will face numerous difficulties in his future life.
Problems can arise in different areas. For example, in work, finances, personal relationships.
But wishes for health, happiness and good luck are unlikely to come true.
Therefore, congratulate the person on his/her birthday precisely during the celebration. In extreme cases, do it one or two days later. But not in advance.
