The release mentions March 10th, 5 pm (so like end of day, meaning that is included in the 30 calendar days) as the last time to excercise.

Counting backwards 30 calendar days, this means that the first day of that interval would be Feb 9th. And that would be "following the triggering of the Warrant Acceleration". 

Now, anyone take it as they want, triggering could be interpreted as a day btw Feb 3-9.

When exactly (a few days difference) it is not that relevant anymore; the important take is that it has been triggered and we have a clear end day, imho.
