+## Utility Methods
+
+### Date Comparison
+
+We provide four utility methods for date comparison:
+```
+  isInclusivelyAfterDay
+  isInclusivelyBeforeDay
+  isNextDay
+  isSameDay
+```
+
+Each of these methods takes in two moment objects and returns a boolean, indicating whether the first argument is inclusively after, inclusively before, the day immediately after, or the same day as the second argument.

If you were using [sass-loader](https://github.com/jtangelder/sass-loader) with webpack, the code below would properly override the selected variables:
