On weekly.prompts.com, I found the one-day prompt for February 28th.
The word is “One Day”. The details you can find on https://weeklyprompts.com/2026/02/28/weekly-prompts-the-one-day-prompt-21/

One Day, I will make my dreams come true.
Yesterday is already gone.
Today, I am to busy for it.
Tomorrow, I will be too tired.

But one day, may be someday
I will do what I want
Not looking for money
Not caring about what others think

Is Monday one day?
Or is it Tuesday?
Wednesday or Thursday?
Friday?
Or Saturday or even Sunday?

Ok, all days are almost gone.
I just dare, that One Day will come.
Before my last will arrive.
