I am a beginner in software testing.

I was going through the .yml file used to schedule the regression runs and came across this:

schedule: "H 1 * * 1,4"

I know about cron format, but what I can not figure out is what is the "H" denoting here, surely it is not every minute (0-59) or else simply a '*' would have sufficed.

Could anyone give a bit of explanation here?

H stands for Hash

H ( H ) 'H' is used in the Jenkins continuous integration system to indicate that a "hashed" value is substituted. Thus instead of '20 * * * *' which means at 20 minutes after the hour every hour,

'H * * * *' indicates that the task is performed every hour at an unspecified but invariant time. This allows spreading out tasks over time
