I need to schedule a process to run every 360th day of the year. According to this there is a field to add year related options. But I am unable to figure out how to schedule it with 360 days duration.
Can someone help to find how to write the cron job to schedule a process to run every 360th day?
for every 360 days following expression will work
0 0 12 1/360 * ? *

I am trying to create a Cron Expression for running job every 4 hours starting at 4pm, but should not run between 12am to 7am of the day.
So far I tried to do this but it does not work.
0 0 16/4 ? 0-2,7-23 * * *
This could be your cron expression.
0 0 16/4,20,8,12 ? * * *
Use this link to get exactly what you are seeking for. It will also helps you with the next execution time.
I want to create a cron expression which will run the scheduler every 2.5 min of every hour. e.g. 2.5min, 5.0min, 7.5min, 10.0min etc. of every hour.
I am using Spring to create the scheduler. I tried various combination but nothing worked. One of them is as below but it is not working.
#Scheduled(cron = "*/30 */2 * * * *")
Thanks in advance.
That should works for you
0 0/5 0 ? * * *
30 2/5 0 ? * * *
At second :00, every 5 minutes starting at minute :00, at 00am, of every day
At second :30, every 5 minutes starting at minute :02, at 00am, of every day
You are right in this case you need to schedule your task twice using expression like on example.
There is a danger of becoming fixated on the 30 seconds. My problem was that I needed to check 18000 records for updates every month ~ 1 record every 2.5 minutes. I spent too much time trying techniques to run a job at exactly 02:32:30 before I realised that accuracy was not important.
In my situation, I realised I could execute every 2 minutes, updating my full database every 25 days instead of every 31 days.
Alternatively, I could have had 2 cron jobs running every 5 minutes. First, a 2-minute gap, followed by a 3-minute gap.
02:30 02:32 02:35 02:37 02:40 02:42 02:45 02:47
My point is that when the cron job is live, it runs unseen. Obviously, everyone has their own specific problem, but before introducing complexity, consider if it is necessary. As long as the job executes, does it really matter the exact time it ran?
In AWS glue service there is an option to trigger job by custom CRON expression. Before i used this (0/2 * * ? *) cron expression to trigger job for every 2 hours.
Now I need to change the cron expression to trigger every 90 minutes, i.e for every 1 and a half hour. I tried with many cron expressions but that did not triggered for every 90 minutes. Even if i give for 90 minutes, it trigged for every 1 hour.
Can anyone help me out by providing the correct cron expression to trigger job for every 90 minutes ?
You can use the following pattern which was based on Bill Weiss' answer on Server Fault. It was modified to comply with the unique syntax AWS uses (reference here):
0 0-21/3 * * ? *
30 1-22/3 * * ? *
You'll have to define two separate Glue Triggers to accomplish this, each with the same job settings.
If curious, the syntax reads:
Run every 0th minute for every third hour for 0-21 hours
Run every 30th minute for every third hour for 1-22 hours
In mule, I need to poll once in 48 hours.
I wrote the cron expression 0 0 1/48 ? * * but it is running twice in 48 hours, i.e, once in 24 hours.
Can anybody suggest exact expression?
You can also make use of cron maker.

You can use 0 0 0 1/2 * ? * to poll once every two days at 12 AM. The 3rd value from right can be used to specify that at what hour you want to poll once every two days.
One thing I can notice in the cron expression you are using is you are putting 1/48 at wrong position.
The cron expression has specific place for unit of time.
Minute Hour Day Month Weekday
if you want to execute the job every 48 hours you should something like this :
0 */48 * * *
or if you want to execute the job once in 2 days then you could use something like below:
0 0 */2 * *
Let me know if this is helpful for you.
We need to produce Azure CRON Expression to start job at certain date between a start and end time at intervals of hours or minutes.
So say if I want the job to run every 30 mins starting from 7:30 AM to 1:30 PM everyday, my expression should go like below?
0 30/30 7-13 * * *
And to run every 2 hours starting from 7:30 AM to 1:30 PM everyday, my my expression should go like below?
0 30 7-13/2 * * *
Is it possible to achieve these with Azure CRON at all? If not what's my alternative?
The CRON Expressions are not Azure specific but CRON specific.
First you need to get deep into the cron and understand how it works and what does the cron expression mean here. Then you can use tools like CRONTab Guru here to get to your expression.
To get to something that might be the one you search for:
0,30 7-13 * * *
This expression is read:
“At minute 0 and 30 past every hour from 7 through 13.”
Which is basically every 30 minutes starting at 07:00 and ending at 13:30.
You can give yourself a try with the CronTab Guru and find the best suiting formula for you.
