Incorrect Output from formatDistanceToNowStrict or formatDistanceToNow for Week Duration

[zcmgyu]

Description:

When using the formatDistanceToNowStrict function from date-fns to calculate the distance to the current time from a date that is exactly one week ago, the output is incorrectly displayed as “7 days” instead of “1 week”.

Steps to Reproduce:

1. Subtract 7 days worth of seconds from the current date to simulate a date that is one week in the past.
2. Use the formatDistanceToNowStrict function to calculate the distance to now from this past date.
3. Observe the output logged to the console.

Expected Result:

The output should be “1 week” to accurately reflect the duration of one week.

Actual Result:

The output is “7 days”, which does not align with the expected week-based formatting.

Code to Reproduce:

const date = subSeconds(new Date(), 7 * 24 * 60 * 60);
const output = formatDistanceToNowStrict(date);
console.log('DEBUG output: ', output);
// DEBUG output:  7 days

Additional Information:

date-fns: 3.6.0

judging from the documentation, it seems right to have the output as "7 days" instead of "1 week".
