I need to run a script at 2 pm on the end of every month. The reason i set 2 pm is i've a timezone of asia/calcutta and it differs 10 hrs and 30 min. from the server time.
I've set date_default_timezone_set('Asia/Calcutta') in my script, so for the current settings i can trigger 1st day of every month as per my timezone.
But the issue is, i'm using webmin and there is no settings to run end of every month and only date from 1 - 31 listed. Here i attached the screenshot.
How can i run the script on end of the every month at 2pm?
Any help greatly appreciated, Thanks!.
The simple way, but ugly
is set to run on every 28,29,30,31 days. Each time when script is launched compare current day with max days in current month using bash/oerl script
Have it run every day starting the 28th of every month through the first of the next month. In the script, check if tomorrow is the first day of a month. If so, run, else die.

please i want to create crontab that should runs evry 14th working day at 10am.
Im tried this row but still not giving what i want.
0 10 14 * 1-5
Thank you in advance
This will make it run on the 14th of the month (if that day falls between monday and friday)
0 10 */14 * 1-5
If you want it to run every 14 working days, you might want the cron job to call a script. Tell cron to run every day at 10. The script can then keep track of last time it ran, compare it and run if it's been 14 days and if today is a weekday.
I wish to schedule a airflow job for specific set of dates every month, for example 11th and last day of every month and used the below scheduler expression
25 14 11,L * * # At 2:45 pm on 11th and last day of every month
When I validated the above in https://crontab.guru/ and http://cron.schlitt.info/ i was told the expression as invalid.
Is it possible to schedule together for a known and a unknown (here last) day of every month? If not is there any other way to achieve this?
maybe your cron does not support the "L" flag. you can refer to this CRON job to run on the last day of the month
my task is to make a script which does server snapshots once a day for 7 days, then
once for a week for 3 weeks moving to once for a month for 12 months. And the question is how can I change
frequency of doing snapshots in CRONTAB without changing CRONTAB manually after 7 days then 1 month etc.
I'm afraid that this is three separate entries in the cron table, including start and end time/date. Coding this as a continuing time check from the start date is simply overkill, unless you have some need to restart this sequence every 3-12 months.
I am working on Quartz Scheduler where need to trigger my job on basis of monthly where user can select desired month date from which he want to make it run for every month on that particular date. lets say- I want to schedule quartz job from August 20,2015 which should run every month on 20th, but it should not start by today,must be start on August 20,2015 onward. what would be the cron expression for this?
I have tried a lot to find out the matching thread but did not worked for me.
like if i have to make for every month which start on 20 May 2015 and repeat every 20th date of month the cron expression would be [0 0 12 20 1/1 ? *].for this requirement lot of things available around and works nicely. but how to schedule Quartz which must fire on particular date and repeat onward for every month on that particular date and time?
Please help me out.any link or any guideline would be appreciable.
I have cronjob to be run on every month first friday evening
i used the below mentioned entry
00 20 1-7 * Fri [ "$(date '+\%a')" = "Fri" ] && $HOME/path/to/my/script.sh > /dev/null 2>&1
This entry should run my script if Friday falls withing 1-7 day of the month, but my script is getting executed even after 7th (i.e on all Fridays of the month).
Please suggest how to fix it.
This is because when you specify a day of month and day of week, cron will execute the job when EITHER of those constraints are true. From the man page for crontab (5):
Note: The day of a command's execution can be specified by two fields —
day of month, and day of week. If both fields are restricted (i.e.,
aren't *), the command will be run when either field matches the cur‐
rent time. For example,
``30 4 1,15 * 5'' would cause a command to be run at 4:30 am on the 1st
and 15th of each month, plus every Friday.
There isn't a direct way in cron to do what you want, but cron : how to schedule to run first Sunday of every month describes a workaround by using cron to run your script e.g. every Friday and then calculating in the script if the day of month is in the range 1-7, and only continuing when that is the case.
In response to the comment about using 5 rather than Fri to specify day of week: using Fri is OK, as the man page says:
Months or days of the week can be specified by name.
