Hi sapevi! You don't have to specify the dates on which you want to use your Swiss Flexi Pass in advance. You do have to mention the start date (April 18) in most cases when ordering, but that's all. From April 18, your Swiss Flexi Pass is valid up to and including your last fee travel day, which in that case would be April 24. You can decide for yourself which day is your last free travel day, as long as it's within one month from the start date.
In between the first (April 18) and last (April 24) free travel day, you can choose 4 other days (assuming you've ordered a 6 day pass) to count as free travel days. According to your itinerary these days would be April 20, 21, 22 and 23. You don't have to fill out these dates in advance: you can do so on each free travel day before boarding your first train/bus/boat of that day. Depending on the reseller, you can either write down the date yourself or have it stamped by a railway official, but you'll receive instructions on this along with your pass.
On all remaining days of the Swiss Flexi Pass validity (which in this case is April 19 only), a 50% discount applies, and for this discount nothing has to be written down or stamped. It's no problem if you don't use your pass at all this day.
Does this answer your questions?
