I want to create a job which deletes records from a database after a period of time has passed. For example I have a field in news table Time Stamp
and each month a SQL query runs like a scheduled job against my database and deletes news where the time stamp is two month old. Generally I want to delete news for 2 month ago and older to not let my table become a large table. How can I accomplish this?

you should create a job in SQL below is a sample T-SQL for create a job via SQL agent
USE msdb ;
GO
EXEC dbo.sp_add_job
@job_name = N'Weekly Sales Data Backup' ;
GO
EXEC sp_add_jobstep
@job_name = N'Weekly Sales Data Backup',
@step_name = N'Set database to read only',
@subsystem = N'TSQL',
@command = N'ALTER DATABASE SALES SET READ_ONLY',
@retry_attempts = 5,
@retry_interval = 5 ;
GO
EXEC dbo.sp_add_schedule
@schedule_name = N'RunOnce',
@freq_type = 1,
@active_start_time = 233000 ;
USE msdb ;
GO
EXEC sp_attach_schedule
@job_name = N'Weekly Sales Data Backup',
@schedule_name = N'RunOnce';
GO
EXEC dbo.sp_add_jobserver
@job_name = N'Weekly Sales Data Backup';

You will need to create a SQL Agent Job to schedule a job to periodically run. If you want to create the job with T-SQL, refer to How to: Create a SQL Server Agent Job (Transact-SQL).
