Hi there , i want to create a Countdown for the Hours of work left and can’t get it together
the work hours from 10.00 am to 18.30 pm . I would like to have it, so it counts down how many hours i have left … Any Hep always highly appreciate it

Also maybe someone can help me with a Birthday countdown for instance mine would be 11.03

Here is a start for your work day:
(floor((((18*60)+30)-((#DH#*60)+#Dm#))/60)):(round(((((18*60)+30)-((#DH#*60)+#Dm#))/60)%1*60))

It shows as 1:20 for an hour and 20 minutes left (it does not have leading zeros yet, so 1:5 for 1h05m).
You can choose to only show it from 10 till 18:30 with the following formula in the opacity field:
$((#DH#*60)+#Dm#)>=(10*60)&&((#DH#*60)+#Dm#)<=((18*60)+30)?100:0$
