Aurelia Framework has a lot of built in observers to efficiently track object changes and proceed with view update but some things are not implemented yet.
I found one missing functionality during schedule application development. Missing Date object fast observer.
By the way Aurelia has a perfect plugin system, so this problem could be fixed very easy.
I would like to announce
aurelia-date-observer plugin for Aurelia Framework which allow to efficiently track Date objects changes.
jspm install aurelia-date-observer
And then activate plugin in main.ts or main.js:
More details could be found on project homepage
