How to set node-cron to run in 12 hours - node.js

I wish to schedule a task in my node.JS project to run in 12 hours from the time of schedule. I tried using 0 */12 * * * but it can only run at the 12th hour. How to do please?

You can give a try to Bull.js. I never used it for scheduling task (only one task after xx minutes). But according to their documentation, you can schedule/repeat a task.
Example code:
paymentsQueue.process(function(job){
// Check payments
});
// Repeat payment job once every day at 3:15 (am)
paymentsQueue.add(paymentsData, {repeat: {cron: '15 3 * * *'}});

Quite easy to use as it follows cron expression descriptor

How to use both Cron and Rate expressions for scheduling CloudWatch rules

I would like to schedule a trigger for a AWS Glue job using CloudWatch schedule expressions. The requirement is to schedule the trigger to run every 3 hours between 8am and 6pm. I don't see any possible option of configuring this. Using the following expression, I can only schedule it between 8am and 6pm, but how can I configure the rate to be 3 hours instead of every hour?
cron(0 8-18 ? * * *)
The desired rate is to scheule it to run at 8am, then 11am, then 2pm, then 5pm.
This should work for you:
0 8-18/3 ? * * *

Cron Schedule for a job that runs every minute from 8 am to 7:30 pm

I can't figure out how to create a job that ends at a specific hour and minute
If you break your cronjob into two, it would look like:
* 8-19 * * * command
0-30/1 19 * * * command
first line runs every minute from 8-19, and second line every minute from 19-19:30.
Cron triggers are not quite suitable for these types of schedules. If you do not insist on using a Cron trigger, I recommend that you check the Daily Time Interval trigger that is designed for use-cases such as yours. I am attaching a screenshot of a Daily Time Interval Trigger configuration for your use-case.

Azure function CRON Schedule expression

If I wish to run my function app at 11.15 PM to next day 1.15 AM(That mean MONDAY 11.15 PM start and TUESDAY 1.15 AM will end) and it will trigger every minute during this time.
Can anyone help me to write this CRON expression?
The timer triggers are designed for a single repeating interval. The only way to do this completely within a Function is to run the trigger once per minute, then abort if the current time isn't in the desired target time period.
Alternately, put your logic into an HTTP trigger configured to act as a webhook, then use an Azure scheduler to configure start and stop times and intervals.
You won't be able to use the scheduler free plan since it can only run once per hour, but the standard plan can run once per minute. Scheduler pricing here.
You'll have to do this in three lines I think,
15-59 23 * * *
* 0 * * *
0-15 1 * * *
This will run it from 23:15-23:59 then 00:00-00:59 then 1:00-1:15

Quartz Cron syntax: every 10 mins between 8am and 4:30

I'm trying to write a Quartz task that runs on a cron schedule of every 10 minutes between 8am and 4:30pm.
If It was just between 8am and 4pm I would use
s m h dom M dow
0 */10 8-16 ? * MON-FRI
But I need it to run until 4:30 not just 4...
How can I do this?
I think it is impossible to express such requirement in one cron schedule . I would create two cron schedules instead :
0 */10 8-15 ? * MON-FRI (Run from 8:00am to 3:50pm every 10 minutes)
0 0,10,20,30 16 ? * MON-FRI (Run at 4:00pm , 4:10pm , 4:20pm , 4:30pm)
In this particular case you are probably better off using a DailyTimeIntervalTrigger rather than a CronTrigger. Here is a screenshot from QuartzDesk (our Quartz management and monitoring GUI) that shows you an example of a DailyTimeIntervalTrigger with attributes that meet your scheduling requirements:

Run a cron job every minute only between 10 am to 5 pm

How do you run a cron job every minute only between office hours(10 am to 5pm)
I checked this thread Run a cron job every minute only on specific hours? but it doesn't answer my questions.
This should be correct:
* 10-16 * * 1-5 /path/to/my-script
So every single minute, between and including 10am and 5pm, every day in every month that is a day between and including monday to friday. Obviously "office hours" is a fuzzy expression, many people have other schedules ;-)
Unfortunately I fail to see an easy solution to get the script executed also exactly on 5pm...
* 10-16 * * * /path/to/executable/file argument_1 argument_2
Yes, you can define hours range.
Someone tried to edit my answer but as documentation says hours in range are inclusive http://team.macnn.com/drafts/crontab_defs.html so don't change 16 to 17.
It does,
Access your shell script and add the following
* 10-17 * * *
This means run every min, between these hours, on every day, of every month etc
