Yes, 23rd December is the day when the transfer of funds becomes available. This is due to the fact that many banks and financial institutions offer a transfer window in which customers can transfer funds from one account to another. This window is typically open for a short period of time and closes on the same day. This means that customers can take advantage of this window to transfer funds from one account to another. This is a convenient way to move money from one place to another without having to go through the hassle of setting up a new account or transferring funds manually.
