I want to create a cron job in Hybris that can run 5 days before the month end.I'm do some using
0 23 22-31 * * [ $(date -d +1day +%d) -eq 1 ]
What is equivalent to this in hybris cron job impex configuration.
hybris uses Quartz 2 as shown in the documentation.
From Quartz 2 documentation :
The ‘L’ character is allowed for the day-of-month and day-of-week fields. This character is short-hand for “last”, but it has different meaning in each of the two fields. For example, the value “L” in the day-of-month field means “the last day of the month” - day 31 for January, day 28 for February on non-leap years.[...] You can also specify an offset from the last day of the month, such as “L-3” which would mean the third-to-last day of the calendar month. When using the ‘L’ option, it is important not to specify lists, or ranges of values, as you’ll get confusing/unexpected results.
So you can use that 0 0 0 L-5 * ?.
Note: on older hybris version (v4) I'm not sure Quartz 2 was available. With Quartz 1 you can't use the L-x pattern.
If you want exactly 5 days before end of month you should create 3 triggers.
0 0 20 26 1,3,5,7,8,10,12 ? * -> the 26th at 20h for all 31 days month
0 0 20 25 4,6,9,11 ? * -> the 25th at 20h for all 30 days month
0 0 20 23 2 ? * -> the 23rd at 20h for february, this is actually a corner case because you may have different day for february...
There is also an other solution, but much more complex.
You can set a trigger for the first time it needs to run. Then in your job you can access a LocaleDate object to determine the next time the job should trigger. Finally update the trigger of the cronjob with Java code or impex creation+import.
I found better solution , using quartz
0 0 0 L-5 * ? *

This is more difficult than I thought. In the month of September 2022, I need cronjobs to run on the 1st, 3rd and 5th Thursdays (there are 5 Thursdays this month!), but in October 2022 I need them to run on the 2nd and 4th Thursdays.
I would like my tasks to run every 2 weeks without skipping any days when a month has 5 Thursdays
How can I accomplish something like this with a cronjob? Is it even possible?
You can do cron on odd/even week of month.
#Every day except Thursday at 1am
0 1 * * 0,1,2,3,5,6 yourCommand
#Every Thursdays at 1am, proceeds only on even weeks
0 1 * * 4 test $((10#$(date +\%W)\%2)) -eq 0 && yourCommand
#Every Thursdays at 6am, proceeds only on odd weeks
0 6 * * 4 test $((10#$(date +\%W)\%2)) -eq 1 && yourCommand

I have Timer Trigger Azure function, which I want to trigger on 2nd Sunday of every month. what should be the cron expression for it?
I have tried below ones but it's showing as wrong format of cron expression
0 0 0 ? * 7#2
0 0 0 ? * SUN#2
The second Sunday of the month falls on one (and only one) of the dates from the 8th to the 14th inclusive. Then the cron expression will be easy to get it.
Suppose it should be 0 0 0 8-14 * Sun and the below is my test, it shows the first five date.
From the picture suppose the expression should be right, hope this could help you.
I need a cron expression that will fire every second day excluding weekends.
Example:
The schedule starts on Monday. The schedule continues in the following manner:
(1st week) Monday>Wednesday>Friday
(2nd week) Tuesday>Thursday
(3rd week) Monday>Wednesday>Friday
(4th week) Tuesday>Thursday
Is that possible using only cron? I know a solution would be to run it every day and when it runs on weekend 'manually' prevent it from running.
Maybe something like could help...
* * 1-31/2 * mon-fri command.sh
That means, "At every minute on every 2nd day-of-month from 1 through 31 and on every day-of-week from Monday through Friday."

I will consider extended expression format so your query will looks like:
S M H DoM M DoW Y
0 0 10 1-31 * 1#1,3#1,5#1 *
This query can be understood as: Repeat at 10:00:00 every day of every month where day of week is (monday, wednesday, friday) and it's first week of month.
You would define such 4 queries (i'm considering that 1 in 1#3 is just monday and 3 is week number in month):
1.) 0 0 10 1-31 * 1#1,3#1,5#1 *
2.) 0 0 10 1-31 * 2#2,4#2 *
3.) 0 0 10 1-31 * 1#3,3#3,5#3 *
4.) 0 0 10 1-31 * 2#4,4#4 *
which runs the same command. But it won't work becouse of limitations of most of evaluators (as i guess).
If you are familiar with .NET, I made evaluator which handle such expressions correctly, but it's only evaluator so what you only receive are dates when your event should occur. There is no job sheduler integrated with it. Click
I had a question before 1 month regarding this. that was the interval of 1 hour and i got exact answer. below is the link to the old question
How to set a Cron job in Every one hour from 9:00 am to 6:00 pm ( Monday to Friday )
Thank you Stack Over Flow and the contributor Andy Holmes
Now I got a new requirement on Cron expression, the same way i need it in every 2 hour.
I have tried
0 9/2-18/2 * * 1-5
and
0 (9-18)/2 * * 1-5
But that doesn't help, Please help me
Use:
0 10-18/2 * * 1-5
You specify the hour range 9-18 and then /2 to mean step by 2 hours. The man page explains this pretty clearly:
Step values can be used in conjunction with ranges. Following a range with /<number> specifies skips of the number's value through the range. For example, 0-23/2 can be used in the hours field to specify command execution every other hour (the alternative in the V7 standard is 0,2,4,6,8,10,12,14,16,18,20,22). Steps are also permitted after an asterisk, so if you want to say "every two hours", just use */2.
If your interface doesn't allow this shorthand, you have to list them out by hand:
0 10,12,14,16,18 * * 1-5
How do I set a cron job to run twice a week?
I know how to set a cron job for every week:
0 0 * * 0
How about the following:
0 0 * * 1,4
This sets the day of week to Monday (1) and Thursday (4). You can choose any values 0–7 (both 0 and 7 are Sunday).
For a more readable crontab, you can also use names:
0 0 * * MON,THU
See also: How to instruct cron to execute a job every second week?
In reply to Elby question :
0 0 1,15 * *
This will set cronjob for (fortnight) 2 times in a Month i.e 1st day and 15th day of a month.
These answers are great, but I wanted to share a tool I found right after looking at this question and answers called crontab.guru. I'm not affiliated, I just thought it was a nice tool.
crontab.guru for 'At 00:00 on Monday and Thursday.'
