Send one message that says which of two things you are doing: declining and naming a date, or declining without one. The date comes from the posted roster, not from hope. Under Oregon's predictive scheduling rule, employers in retail, hospitality and food services with at least 500 employees worldwide give the written schedule 14 calendar days in advance, so a worker covered by it can name a real day inside those two weeks. Without a rule like that, you name the day the schedule posts instead.
Pick the message before you write it
The three answers below differ in what they commit you to, so choose the row first and then write the sentence.

| Message | What it commits you to | Send it when | What you need back |
|---|---|---|---|
| Decline and name a date | One specific day and time you can hold | The next schedule is already posted | A yes or no to that day |
| Decline and name the posting date | Only a date on which you will answer | The roster lands on the 20th and the plan is after that | Nothing until the 20th |
| Ask them to move this one | The same plan at another hour | The plan itself is movable, not the date | A new time from them |
The difference matters to the other person more than the wording does. "Soon" reads as a maybe and sits in their calendar as one. A date, or the date you will have a date, closes the question either way.
The date you name has to survive the roster and your sleep
Two things cancel a plan after you have agreed to it: a schedule change and the sleep it eats. Oregon's rule prices the first one. The state's predictive scheduling page says an employer that adds more than 30 minutes of work, or changes the timing of a shift without losing hours, owes one hour at your regular rate, and that a canceled scheduled hour pays one-half your regular rate per hour. It also gives a 10-hour break: work in the first 10 hours after the previous calendar day's shift pays one and a half times your normal rate. Those numbers tell you which weeks are volatile and which are not, and what to do when a shift moves at the last minute starts from the same page.
Sleep decides the hour. NIOSH's night-shift module tells nurses to sleep on arriving home after a night shift, for example at 8 a.m., and on days off to stay up until 3 or 4 a.m. and sleep until noon or 1 p.m. so that the same hours stay sleep hours in every 24. An 11 a.m. brunch on your day off is inside that window. A 3 p.m. coffee is not.
One worked example: the invitation for the 5th
Example. You work grocery retail in Portland, the roster for the 5th to the 18th posted on the 20th of the month before, more than 14 days ahead of its first day, and a friend asks about dinner on the 5th. You are on 2 p.m. to 10:30 p.m. that day. The 6th is off, and the 10-hour break rule means nothing starts before 8:30 a.m. on the 6th anyway. You reply: "Can't do the 5th, I'm on until 10:30. I'm off the 6th and free from 2 p.m., is dinner at 6 p.m. that day any good?"
When the roster is not out, the second message is the honest one: "Our schedule posts on the 20th. I'll tell you on the 20th whether the 5th works." Then answer on the 20th, whichever way it goes.
Give people the pattern once instead of explaining it every time. NIOSH's coping module suggests marking your work hours and likely sleep times on the home calendar or on cards you hand out, which is the same move as a shared calendar showing free blocks and nothing else. That way your availability goes out without the reasons attached, and the people who invite you learn the shape of your week.
Write the message with both clock times in it: the hour you are free and the date you will know. "Off the 6th, free from 2 p.m." and "I'll answer on the 20th" are the two sentences that keep a plan alive. The evening offers that fit night work start from the same two.
