First of all, for the owner of a birthday, a birthday is to celebrate a special day in life, usually an occasion full of joy, blessings and love. Moving is an action to change the living environment and may bring new opportunities and challenges. If the birthday host thinks that holding these two activities on the same day will bring too much pressure and interference, or that moving may dilute the focus of birthday celebration, then consider moving on the second day or a few days before the birthday.
On the other hand, if the birthday host and family or friends think that these two activities can be held on the same day, they can also make arrangements according to their own wishes. In this case, you can try your best to make proper arrangements for moving and preparing for your birthday to ensure that everything is completed smoothly on the same day.
In short, how to deal with this situation depends on personal preferences and circumstances. If you have any questions or uncertainties, you can consult your family or seek professional advice.
