In this example, we first import the dayToWeeks function from the date-fns library. We then create a Date object representing a date 14 days from January 1, 2022. Finally, we use the dayToWeeks function to convert the 14 days to weeks and store the result in the weeks variable. We then log the number of weeks to the console.
