I am working on a schedule for a TV series with eight episodes shot in 4 Blocks (2 episodes per block). There are three days in the middle of Block 1 that will be Block 2 work, and then Block 1 continues. Explanation: June 9-23 is Block 1, June 24-26 is Block 2, June 27-30 is Block 1 again, and July 1-25 is Block 2. How can I reflect this on a board and keep track of Block 1 and 2 production days so that June 24, 25, and 26 will be Block 2, Day 1, 2,3, and June 23 will be Block 1, Day 11, and June 27, Day 12.
