Extract date range from cell and populate 'calendar-style' in separate tab

I would like to extract a start date (e.g. 1/1/19) and duration (e.g. 10 days) from a single cell to a separate tab that is set up like a calendar (1 row to a day from 1 January onwards). Is it possible to get the date range to fill the 10 rows for 1-10 January?

File attached - this particular spreadsheet tracks the number of days a contractor is at a commercial jobsite. For example, John Smith is at Jobsite A 1-10 January. On the Construction Planner tab, I have the dates in the first column for 1 January onwards, each day to a row. I would like the date data in Client Planner tab to populate across to fill John Smith's column for 1-10 January.

Tough ask but I thought I would start here to see if anyone knew if something like this is possible! Thanks in advance
