Cron expression at 8:00 and 16:30 from monday to friday - azure

How can I write a CRON expression that will invoke Azure WebJob Monday through Friday at 8:00 AM and 4:30 PM?

You can have a job triggering at 8AM and 16PM Monday through Friday using
0 0 8,16 ? * MON,TUE,WED,THU,FRI *
If you definitely need 16:30, you will need 2 CRON triggers.
0 0 8 ? * MON,TUE,WED,THU,FRI *
0 0 16 ? * MON,TUE,WED,THU,FRI *
You can check your CRONs HERE.
As mentioned in this existing question, Single CRON is possible if the minute triggering is the same.

Recently I have used this and it worked for me:
0 3 * * 1-5
The above format is basically-
(min) (hr) (day in month) (month) (day in week)

To run in a time window until midnight

I have an AirFlow scheduler that I want to run at 13 until midnight from Monday to Saturday. I wrote an expression like this:
0 13-0 * * 1-6
While trying to validate this in crontab.guru for example I get an error since 0 is smaller than 13:
https://crontab.guru/
Does anyone know how can I write a valid cron-expression for this type of schedule?
If you would like to run your command at minute 00 from 13:00 onwards till midnight (inclusive) on all days except Sundays, then you have to play a trick. It is not possible to define the hour 24 in a crontab. You can define the hour 00, but a crontab of the form
0 0,13-23 * * 1-6
will run on Monday 00:00 and not on Sunday 00:00 which is what the OP really wants.
Here are two methods you can use:
Run two crontabs:
0 13-23 * * 1-6
0 0 * * 2-7
Run a single crontab a minute earlier:
59 12-23 * * 1-6
How about: 0 13-23 * * 1-6
“At minute 0 past every hour from 13 through 23 on every day-of-week from Monday through Saturday.”

Cron Expression for every second Monday of the month (for Hangfire)

I am trying to create recurring job in hangfire that runs, once a month at the second Monday, something like this:
1. Monday, May 14, 2018 8:00 AM
2. Monday, June 11, 2018 8:0 AM
3. Monday, July 9, 2018 8:00 AM
4. Monday, August 13, 2018 8:00 AM
5. Monday, September 10, 2018 8:00 AM
I have found this answer in stackoverflow, but since this is not a standard cron for scheduling hangifre jobs I can not use it.
My question is can I make an expression like this using the format
* * * * * (min hour day/month month day/week)
The following command seems to work for me.
0 8 ? * MON#2
Assuming that you want this job to execute at 8 AM the second Monday of each month, the # character allows you to specify the "nth" day of any given month. We use the ? character in the day/month row since we are fine with any numeric day as long as it is the second Monday.
Read more about special characters here: http://www.quartz-scheduler.org/documentation/quartz-2.2.2/tutorials/crontrigger.html#special-characters
Below are cron for three different time for every 2nd Monday, Look into the pattern and make change in time as per your need day
For each second Monday of the month at 00:00 hrs, try below:
0 0 0 ? 1/1 MON#2 *
For each second Monday of the month at 10:30 hrs, try below:
0 30 10 ? 1/1 MON#2 *
For each second Monday of the month at 13:30 hrs, try below:
0 30 13 ? 1/1 MON#2 *
Here you go.
0 0 12 ? 1/1 MON#2 *
minute hour day month dayofweek command
0 0 8-14 * 2 /path/here
This will run a job every second tuesday of the month at midnight.
8-14 limits the occurance of tuesday to the second week in the month.
1-7 first week
8-14 second week
15-21 third week
22-28 forth week
29-31 fifth week

Quartz Cron expression :Run every 15 days ie twice in a month

I want to set the scheduler with a quartz cron expression which will trigger every 15 days ,for example 1st and 15th of every month.The 0 15 10 15 * ? is triggering only on 15th of every
month.
I have tested this and the following expression works fine
"0 0 0 1,15 * ?"
the 1,15 statement fires triggers on 1st and 15th of every month at 00:00 hours.
You can change the first three zeroes to fire them at a particular time you want.
the 1st zero -> seconds
the 2nd zero -> minutes
the 3rd zero -> hours
0 0 1,15 * *
“At 00:00 on day-of-month 1 and 15.”
0 0 1,15 1 *
“At 00:00 on day-of-month 1 and 15 in January.”
0 0 1,15 1 6
“At 00:00 on day-of-month 1 and 15 and on Saturday in January.”
The following also works fine, it executes your command on the 15th and the 30th at 02:00 AM of every month:
0 2 */15 * * <yourCommand>
You just need to append 1 with a comma to your expression at 'Day of Month' block.
Rest is fine !
0 15 10 1,15 * ?
This will schedule to run every 1st and 15th day of the month and 10:15 am.

Cron Expression to execute cron triggers for 12 hours of a day?

I need a cron-expression (0 0/60 * * * ?) to fire application every 12 hours (twice a day).
Use e.g. 0 0 3,15 * * ? That'll run a job at 3am and 3pm. That's twice a day, with 12 hours between.
You could use 0 0 0/12 * * ? which means every 12 hours. Here's some examples.
Some examples that fit your criteria:
30 */12 * * *
runs at 00:30:00 and 12:30:00 each day
0 3-15/12 * * *
runs at 03:00:00 and 15:00:00 each day
23 4,16 * * *
runs at 04:23:00 and 16:23:00 each day
