I have written a Lambda to fetch some prices on Nifty Index(share market) which runs every 5 mins and uploads data to S3.
For this i have written a cron using AWS EventBridge schedule given below
15/5 9-15 ? * MON-FRI *
now the problem is this runs from 9-15 AM to 4 PM but i want to run only till 3 - 30 PM daily.
So its running 30 mins extra which is consuming more space on s3 also
Any suggestions? Couldnt find elsewhere
Tried
15/5 9-15 ? * MON-FRI *
Current 9-15 AM to 4 PM
Expectation
9-15AM to 3-30 PM
This 15/5 9-15 ? * MON-FRI * expression will run
At every 5th minute from 15 through 59 past every hour from 9 through 15 on every day-of-week from Monday through Friday.
In your case between each hours 00 and 15 minutes (1X.00-1X.15) this cron will not execute.
So that you need more than one expression to meet your requirements.
30/5 9 ? * MON-FRI * -> From 9.30-9.55
*/5 10-14 ? * MON-FRI * -> From 10.00-14.55
0-30/5 15 ? * MON-FRI * -> From 15.00-15.30

I would like to run Crontab every 30 minutes except from 12 AM - 6 AM EST
The following is to set it every 30 minutes but i don't know how to except the mentioned hours.
*/30 * * * *
Thanks in advance.
I believe you want this rule:
0 0,30 6/1 ? * * *
This runs at 0 minutes and 30 minutes past the hour, and every hour after the 6th hour.
This assumes that your system timezone is in an ET timezone like America/New_York
I need to schedule a job in databricks that should run at 6am, 6.15, 6.30, 6.45, 7, 7.15, 7.30, 7.45 and 8am every day.
I am using below expression however it is not running at 8am. Is there anyway we can achieve this?
0 0,15,30,45 06,07 ? * *
This is expected behaviour from cron expression. As per your requirement, you need to write separate cron expression for the 08:00 as follows:
Note that some scheduling requirements are too complicated to express
with a single trigger - such as “every 5 minutes between 9:00 am and
10:00 am, and every 20 minutes between 1:00 pm and 10:00 pm”. The
solution in this scenario is to simply create two triggers, and
register both of them to run the same job.
This will run from 6.00 until 7.45, every 15 minutes:
* 0/15 06-07 * * *
If you want it to run until 08:00 then you have to create two triggers and register both if them to run the same job.
* 0/15 06-07 * * *
* 0 08 * * *
Reference: Databricks uses Quartz Cron triggers. Databricks – Cron Triggers
Hope this helps.
Run twice a day at 10:00 and 18:00
**0 0 10,18/12 * * ?**

I am trying to create a cron job that fires every 5 minutes before 30, for example:
10:25,
10:55,
11:25,
11:55 etc. I tried */25,55 * * * * but this also sends messages at 10:50 and I'm not sure why, what would be the correct way to do this?
You're looking for the following, which is simply "at minute 25 and minute 55":
25,55 * * * *
In your original attempt, the expression */25 means "every 25th minute". As such, it would execute at 25 minutes after the hour, and then 25 minutes later.. or 50 minutes after the hour.
Right now i am running my cron job everyday at 3.00PM
0 15 * * *
But I want to run my cron job twice in a day. 10.30AM and 2.30PM
0 30 10 * * *
I believe this command will run at 10.30AM. How should i run it in 2.30PM?
Cron utility is an effective way to schedule a routine background job at a specific time and/or day on an on-going basis.
Linux Crontab Format
MIN HOUR DOM MON DOW CMD
Example::Scheduling a Job For a Specific Time
The basic usage of cron is to execute a job in a specific time as shown below. This will execute the Full backup shell script (full-backup) on 10th June 08:30 AM.
Please note that the time field uses 24 hours format. So, for 8 AM use
8, and for 8 PM use 20.
30 08 10 06 * /home/yourname/full-backup
30 – 30th Minute
08 – 08 AM
10 – 10th Day
06 – 6th Month (June)
*– Every day of the week
In your case, for 2.30PM,
30 14 * * * YOURCMD
30 – 30th Minute
14 – 2PM
*– Every day
*– Every month
*– Every day of the week

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:
Lists are allowed. A list is a set of numbers (or ranges) separated
by commas. Examples: "1,2,5,9", "0-4,8-12".
So in this case it would be:
30 10,14 * * *
you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM
1 10 * * * php -f /var/www/package/index.php controller function
30 14 * * * php -f /var/www/package/index.php controller function
but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .
30 10,14 * * * php -f /var/www/package/index.php controller function
If I want to schedule a job to occur every five minutes between 9 until 11 pm I can use the following cron trigger:
0/5 21-22 * * *
(or something like 5,10,15,20,25,30,35,40,45,50,55 21-22 * * * for finer control over the minutes if needed).
Is there a way to specify "every five minutes from 9:30 until 11:30"? The trickiness revolves around having e.g. 5 in the minutes field yet skipping it if the hour is 21, and I'm not immediately aware of any way to achieve that.
A simple, workaround would be to add more scheduled jobs in cron...
i.e.
30,35,40,45,50,55 21 * * * /job_to_run
*/5 22 /job_to_run
5,10,15,20,25,30 23 * * * /job_to_run
p.s. Cron usually has the following order:
Minutes Hour DayOfMonth Month DayOfWeek Command
