(additional detail excised from duplicate): "I have to manually calculate the value of next_run_date based on freq_interval, freq_subday_type, freq_subday_interval, freq_relative_interval, freq_recurrence_factor, etc" – Marc Gravell Mar 08 '10 at 05:26

to get the next run date for a job you can use then sysschedules and sysjobschedules tables
check the next_run_date and next_runtime columns from the table sysjobschedules
next_run_date int Next date on which the job is scheduled to run. The date is formatted YYYYMMDD.
next_run_time int Time at which the job is scheduled to run. The time is formatted HHMMSS, and uses a 24-hour clock.
see this script
Select sched.*,jobsched.* FROM msdb.dbo.sysschedules AS sched
inner Join msdb.dbo.sysjobschedules AS jobsched ON sched.schedule_id = jobsched.schedule_id
or you can use the msdb.dbo.sp_help_jobschedule stored procedure, to get the same info.
UPDATE
if you need calculate manually the next_run_date you must check the sysschedules table and see the freq_interval, freq_subday_type, freq_subday_interval, freq_relative_interval, freq_recurrence_factor, active_start_date, active_start_time columns to determine the formula.
check this link to see an example of use.

`msdb.dbo.sp_help_jobschedule` is much better. `sysjobschedules` doesn’t get updated immediately after a schedule change, at least in SQL Server 2012 SP4. – Dennis T --Reinstate Monica-- Sep 10 '18 at 03:14

Check this one:
SELECT
J.NAME JOB,
DATEADD(SS,(H.RUN_TIME)%100,DATEADD(N,(H.RUN_TIME/100)%100,DATEADD(HH,H.RUN_TIME/10000,CONVERT(DATETIME,CONVERT(VARCHAR(8),H.RUN_DATE),112))))
JOB_STARTED,
DATEADD(SS,((H.RUN_DURATION)%10000)%100,DATEADD(N,((H.RUN_DURATION)%10000)/100,DATEADD(HH,(H.RUN_DURATION)/10000,DATEADD(SS,(H.RUN_TIME)%100,DATEADD(N,(H.RUN_TIME/100)%100,DATEADD(HH,H.RUN_TIME/10000,CONVERT(DATETIME,CONVERT(VARCHAR(8),H.RUN_DATE),112)))))))
JOB_COMPLETED,
CONVERT(VARCHAR(2),(H.RUN_DURATION)/10000) + ':' +
CONVERT(VARCHAR(2),((H.RUN_DURATION)%10000)/100)+ ':' +
CONVERT(VARCHAR(2),((H.RUN_DURATION)%10000)%100) RUN_DURATION,
CASE H.RUN_STATUS
WHEN 0 THEN 'FAILED'
WHEN 1 THEN 'SUCCEEDED'
WHEN 2 THEN 'RETRY'
WHEN 3 THEN 'CANCELED'
WHEN 4 THEN 'IN PROGRESS'
END RUN_STATUS
,CASE S.FREQ_TYPE
WHEN 1 THEN 'ONCE'
WHEN 4 THEN ' DAILY'
WHEN 8 THEN ' WEEKLY'
WHEN 16 THEN ' MONTHLY'
WHEN 32 THEN ' MONTHLY RELATIVE'
WHEN 64 THEN ' WHEN SQL SERVER'
ELSE 'N/A' END [FREQ]
,CASE
WHEN S.NEXT_RUN_DATE > 0 THEN DATEADD(N,(NEXT_RUN_TIME%10000)/100,DATEADD(HH,NEXT_RUN_TIME/10000,CONVERT(DATETIME,CONVERT(VARCHAR(8),NEXT_RUN_DATE),112)))
ELSE CONVERT(DATETIME,CONVERT(VARCHAR(8),'19000101'),112) END NEXT_RUN
FROM
MSDB..SYSJOBHISTORY H,
MSDB..SYSJOBS J,
MSDB..SYSJOBSCHEDULES S,
(
SELECT
MAX(INSTANCE_ID) INSTANCE_ID
,JOB_ID
FROM MSDB..SYSJOBHISTORY GROUP BY JOB_ID
) M
WHERE
H.JOB_ID = J.JOB_ID
AND
J.JOB_ID = S.JOB_ID
AND
H.JOB_ID = M.JOB_ID
AND
H.INSTANCE_ID = M.INSTANCE_ID
-- IF you want to check all job for today then uncomments below

-- RUN_DATE = (YEAR(GETDATE())*10000) + (MONTH(GETDATE()) * 100) + DAY(GETDATE())

The short answer is that there's no single formula - it varies by value of freq_type.
The site seems to be down at the moment of writing, but there is an article at http://www.sqlmag.com/Article/ArticleID/99593/sql_server_99593.html which covers how to derive this information. Unfortunately, the site doesn't allow Google to cache its content, so it can't be retrieved until the site comes back up
This looks like a decent alternative source for the kind of query you're trying to write.
