Question about wait

I have a shell script that i want to run and then wait 30 minutes before running the rest of the script.

When I google the "wait" command, it seems to work for waiting for child processes or some pid to stop.

How do I wait for 30 minutes before continuing?

sleep 1800

normally you can also write :

sleep 30 minutes
# or
sleep 3 hours

@guessingo : type

man sleep
