Get a free numerology reading for both your birth name and the new name you are considering.

Compare the two. Note where they support each other and where there may be conflict.

The two may be highly compatible. Or they may have a number of conflicts.

If this is grabbing your attention as a problem that requires resolution, get a full, professional reading for both your current name and the new name you are considering. Then compare those two.

The full, professional numerology reading has much more depth than the free readings. The more usable information you have, the more control you have over your life.

If the new name seems too conflicting with the person you are or there are elements highly undesirable to you, and if the society where you live permits it, consider keeping your current name without changes after marriage.

Whether or not you decide to change you name, getting the two readings and comparing them is good. At least some of the effects of the new name can be predicted and, if the new name is taken, the changes are expected.

Now, your question about a suitable wedding date.

Many things need to be considered to determine suitability, some of them outside the realm of numerology, like personal preferences and societal expectations. However, the likely marriage dates calculator may help.
