Roblox usually does not “accept” a birthday change request through a long approval process if your account is 13+; you can edit the birthday yourself in Settings > Account Info. Roblox’s help page says you can correct your birthday directly in account settings, and for child accounts a parent can update it in parental controls.

If your account is under 13 or the birthday was set wrong in a way that blocks editing, support requests are commonly reported as taking a few days or sometimes a day or two , based on community guides and videos, but Roblox does not give a firm public turnaround time.

What usually happens

  • 13+ accounts: Change it yourself right away in account settings.
  • Under-13 accounts: You may need parent access or support help, and the wait time can vary.
  • If support is involved: Expect anywhere from 1–2 days to a few days , though it is not guaranteed.

Practical tip

If you already see the birthday field in your account info, the change should be immediate once saved. If you do not see an editable option, then the account likely needs support or parental control access instead.

TL;DR

For most 13+ users, there is no waiting period because the change is done instantly in settings. If support has to handle it, people commonly report a few days of waiting.
