### 5/5 — Works Well!

*2020-02-18, version 2.0*

Very simple app which will calculate number of days between between chosen dates. Very useful for working out utility standing charges, interest payments etc. Previously used Excel, but for quick one off calculation this is just the the job.

### 5/5 — Finally exactly what I needed
