Hi Bobby,
You can do this with Lenvica HRMS's roster module. Create a day program as 08.30 – 11.30 and 16.00-21.00 under, Roster > Regular Day Program.
You can define this created day program for a week/month/year as per your wish under, Roster > Regular Work Planner. Day Offs also you can define there.
Hope this helps.
Regards,
Rijo
