Then you can bring the check back in whenever you're able to.

Just write the check for the date you want it to go to the bank!

[...] If a bank charges against the account of a customer a check before the date stated in the notice of postdating, the bank is liable for damages for the loss resulting from its act.

The loss may include damages for dishonor of subsequent items under Section 4-402. You're writing a future date on the check, not past, to ensure that the check will not be deposited before that day.
