Here's a version that avoids nasty floating point math:

 
include std/os.e 
include std/console.e 
include std/datetime.e 
 
public procedure now_until(datetime dt={2021,12,25,12,0,0}) 
object dt1 -- (computer time and date) 
object dt2 = to_unix(dt)  
object target = datetime:format(dt,"%A, %b %d, %Y %l:%M:%S %p") 
object diff -- in seconds   
integer sec_now = 0, sec_prev = 0 
loop do  
    dt1 = to_unix(datetime:now()) 
    diff = dt2-dt1 
    diff = from_unix(diff)  
    diff -= {1970,1,1,0,0,0} -- adj for unix EPOCH 
    sec_now = diff[6] 
    if sec_now != sec_prev then 
        display("Time remaining: [b]-[b]-[b] []:[]:[]",diff,0) 
        display(" until []",{target}) 
        sec_prev = diff[6] 
    end if 
    sleep(.1) -- note: must check more than once per second, or time will "jitter" 
    until equal(dt1,dt2)    
end loop  
end procedure  
  
now_until()  
 

Now you know how much time you have to buy me a Christmas gift for next year:

Time remaining: 1-4-10 19:37:9 until Saturday, Dec 25, 2021 12:00:00 AM 
Time remaining: 1-4-10 19:37:8 until Saturday, Dec 25, 2021 12:00:00 AM 
Time remaining: 1-4-10 19:37:7 until Saturday, Dec 25, 2021 12:00:00 AM
