To write the date "17. March 2011" in 5 letters without using any numbers, you can use the Roman numeral system. Here's how:

1. Start by converting each component of the date into Roman numerals:
- 17: XVII
- March: Convert March into its respective Roman numeral. In this case, it would be III if we assume March is the third month. (Note that this depends on whether you consider the counting of months starting from January or February. Here we assume March is the third month.)
- 2011: MMXI

2. Now, combine the Roman numerals for the day, month, and year:
- XVII (day) + III (month) + MMXI (year)

So, to represent "17. March 2011" in 5 letters without using numbers, you would write it as "XVIIIIIMMXI".
