Thanks for the PR, @abshakekumar !
I'm merging it into the date-range-filter branch for now since I want to do some editions and after that I'll merge it into master.

we need to update the formatDateLabel function in data.js as
const options = { year: 'numeric', month: 'short', day: '2-digit' };
Because we need year for proper functioning of Date Range Filter.
