In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange.

Setup

Seen with latest code from git while preparing the 1.73 release on Linux, but applies to all platforms.

Expected behaviour

$ python run_tests.py test_PDB_StructureAlignment.py
Python version: 2.7.15 | packaged by conda-forge | (default, Jul 27 2018, 10:26:36) 
[GCC 4.8.2 20140120 (Red Hat 4.8.2-15)]
Operating system: posix linux2
test_PDB_StructureAlignment ... ok

Analogous to how you can use basename to get only the filename of a path, like in:

p.SetOut("out1", "{i:in1|basename}.out.txt")

p.SetOut("out1", "{i:in1|dirname}/newfilename.txt")

This will also allow introducing another level of folders based on a previous
