... etc ..

This is the best I can come up with.  It uses relatively modern Remind
features, so you might need to be running the latest version (3.1.13)

# Note: Strings!
set d1 "2015-01-05"
set d2 "2015-03-19"
set d3 "2015-05-29"
# ... etc

SET t iif(evaltrig(d1) != -1, d1, \
          evaltrig(d2) != -1, d2, \
          evaltrig(d3) != -1, d3, \
          -1)
# ... Add more cases to the iif as necessary

if typeof(t) == "STRING"
   REM [t] PRIORITY 1030 ++5 SKIP MSG %"Biodanza%" %b.
endif

The new features are the "evaltrig" function and the ability to provide
something like 2015-01-05 directly to a REM statement instead of passing
it through trigger() first.  Newer versions of Remind also allow
lines continued with backslashes to be as long as you want which
could be important if you have a huge list of dates.
