Crontab expression for a 8 and a half hour range

Crontab to run a job every minute from 11pm to 7:30am
I have this so far which is every minute from 11pm to 7:00am
the problem is the half hour.
* 23,0-7 * * *
You can play around with it here crontab_guru
Any ideas?
#Dunski : I have checked in many ways this *,0-30 23,0-7 * * * expression could stop at 07:59 min only but not yet 07:30 am.
As #jordanm suggested we have only a way to run two jobs from :
11 pm to 7 am expression * 23,0-7 * * * (“At every minute past hour 23 and every hour from 0 through 7.”) and then
7 am to 7:30 am 0-30 7 * * * (“At every minute from 0 through 30 past hour 7.”).

Run cron job every first minute of every hour

I need to run cron job every hour at first minute
I have already tried the following :
1> 0 * * * * ? *
2> 0 */1 * * * ? *
Unfortunately I did not get correct results
I need the job to start at first minute for every hour as the following :
0:01
1:01
2:01
3:01
4:01
.
.
23:01
end
Every hour at minutes 1
0 1 0/1 ? * * *

How to create cron expression for Hangfire job that executes everyday at some time

I am new to cron expression. All i need to know that how to create cron for recurring job in Hangfire that executes after every 1 day at 5 pm, 1 am, 2:45 pm
Understanding that Hangfire also accepts standard Cron expression, I've tried exploring Cron expressions for this frequency but couldn't find one for it.
I know how it will be done for "every 15 minutes":
*/15 * * * *
I need to run it every day .
The general syntax used by cronjob schedular is :
# Execute the <b>command</b> every minute of every day.
* * * * * command
Explanation of all the fields used by cronjob schedular :
# field # meaning allowed values
# ------- ------------ --------------
# 1 minute 0-59
# 2 hour 0-23
# 3 day of month 1-31
# 4 month 1-12 (or names, see below)
# 5 day of week 0-7 (0 or 7 is Sun, or use names)
Instead of the first five fields, one of eight special strings can be used :
string meaning
------ -------
#reboot Run once, at startup.
#yearly Run once a year, "0 0 1 1 *".
#annually (same as #yearly)
#monthly Run once a month, "0 0 1 * *".
#weekly Run once a week, "0 0 * * 0".
#daily Run once a day, "0 0 * * *".
#midnight (same as #daily)
#hourly Run once an hour, "0 * * * *".
To repeat the job after an interval / is used :
*/15 * * * * command
# This will execute the command after every 15 minutes.
In order to execute the job at specific times, a "," can be used :
* 2,20 * * * command
# This will execute the job every minute but at the hours 2 AM and 8 PM.
Hope that clears your doubts.
I am Trying like:
RecurringJob.AddOrUpdate(() => Console.Write("Recurring"), "*/15 * * * *");

how to increment a cron expression

I have a starting point for a cron schedule and I want to create a new cron expression after a specified time interval.
For example, I start with a cron expression for 1 job as "0 0 12 * * ?"
I need to create a second cron expression for a second job with an interval of, let's say, 30 mins. So it becomes: "0 30 12 * * ?"
Like that, I want to keep incrementing and create multiple cron schedules for different jobs.
So,
1st job - "0 0 12 * * ?"
2nd job - "0 30 12 * * ?"
3rd job - "0 0 13 * * ?"
4th job - "0 30 13 * * ?"
.
.
.
Is there something like: (cron expression 1) + 30mins = another cron expression ?

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
