Solution:   (https://www.mssqltips.com/)

In SQL Management Studio enter this query:

-- list jobs and schedule info with daily and weekly schedules

-- jobs with a daily schedule

sysjobs.name job_name
,sysjobs.enabled job_enabled
,sysschedules.name schedule_name
,sysschedules.freq_recurrence_factor
,case
when freq_type = 4 then 'Daily'
end frequency
,
'every ' + cast (freq_interval as varchar(3)) + ' day(s)' Days
,
case
when freq_subday_type = 2 then ' every ' + cast(freq_subday_interval as varchar(7))
