While this method will change the age on your MS account, if you're looking to change your age on your Xbox account this will not do that. The age listed on your Xbox account is permanent and cannot be changed.

How to change a birthdate on a Microsoft account
Applies to: Microsoft account

For adult accounts (includes most people, in most regions)

1. Sign in to
   Your info on the Microsoft account website.
2. Select Edit date of birth.
3. Change your birthdate, and select Save.

For child accounts, or parents changing a child's birthdate
If your child is above the statutory age (13 in most regions), they’ll need to sign in and update their birthdate using the steps for an adult account. If they're below that age, you can do it for them. Note: If their birthdate
incorrectly shows them over the statutory age, they need to update it as if it's their correct age by using the steps above for an adult account.

1. Using the parent's Microsoft account, sign in to your account on
   family.microsoft.com.
2. At the bottom of the
   Your familypage, select
   Manage my child's profile info.
3. In the Manage permissions page of the child’s account that you want to change, at the right, select
   Edit this child's personal info and then follow the instructions.

For help with age verification, see
Parental consent and Microsoft child accounts.

You can't. If you don't enter the correct age when you create the account, you can not change it later.
