brick/date-time: Date and time library for PHP

If you're happy to bring in another library, you could replace your Date VO class with the LocalDate class from the brick/datetime library. It does the same thing, just has three int fields inside instead of a string in Y-m-d format.

If you need to store subsets of a date-time-timezone combination, then take a look at brick/date-time instead.

Slightly related but https://github.com/brick/date-time is a wonderful library to manage datetime concepts in a proper way.

Looks like a CivilDate is the same thing that brick/date-time calls a LocalDateTime. Does this library have any advantages over the one from Brick?

I like https://github.com/brick/date-time

It is a good practice to use an interface to manage the clock in an application, as it allows having full control of time. For example, it eases testing, as it lets us define the concrete time for each test. Frank de Jonge and Matthias Noback have blog posts about it, brick has an implementation, and there is even a PSR proposal to have a ClockInterface.

Yes there is, I think (haven't used it€. It's called Robo https://github.com/consolidation/robo

Robo: Modern Task Runner for PHP

As a long time user or Robo, could you elaborate a bit on what Blend brings to the table that is lacking from Robo?

Shout-out to Robo as well, which is a nice wrapper around Symfony Console to make it quick and easy to build command-line applications that scale with plugin support.
