Mostly made to try out Dart/Flutter.
|
|
|
|
## Method
|
|
|
|
The day of the week can be caculated by:
|
|
`(day value + month value + year value + century value + leap year value) % 7`
|
|
|
|
Every one of these value comes from a set of constants or is calculable from the date.
|
|
This app helps you practice memorizing and calculating these values. |
