[nitpick] The normalization logic could be simplified by extracting the boundary checking into a separate function. This would make the algorithm clearer and more testable.

val remainder = durationInSeconds % boundary
val difference = if (remainder == 0L) 0L else boundary - remainder
if (difference > 0 && difference <= minuteInSeconds) {
durationInSeconds += difference

[nitpick] The toHumanReadableFormat() method is quite long and handles multiple formatting scenarios. Consider breaking it down into smaller, more focused methods for each time unit range (formatDaysHoursMinutes, formatHoursMinutes, formatMinutes, formatSeconds) to improve readability and maintainability.

I think AI has a point here, the method is quite long, and the multiple branches complicate the code a bit.

I'm suggesting a simpler version below, please check it out:

    private fun Duration.toHumanReadableFormat(): String {
        if (this < Duration.ofMinutes(1)) {
            return resourceProvider.getQuantityString(
                quantity = seconds.toInt(),
                default = R.string.booking_duration_seconds,
                one = R.string.booking_duration_second
            )
        }

        val days = toDays()
        val hours = minusDays(days).toHours()
        val minutes = minusDays(days).minusHours(hours).toMinutes()

        return buildString {
            if (days > 0) {
                append(
                    resourceProvider.getQuantityString(
                        quantity = days.toInt(),
                        default = R.string.booking_duration_days,
                        one = R.string.booking_duration_day
                    )
                )
            }
            if (hours > 0) {
                append(" ")
                append(
                    resourceProvider.getQuantityString(
                        quantity = hours.toInt(),
                        default = R.string.booking_duration_hours,
                        one = R.string.booking_duration_hour
                    )
                )
            }
            if (minutes > 0) {
                append(" ")
                append(
                    resourceProvider.getQuantityString(
                        quantity = minutes.toInt(),
                        default = R.string.booking_duration_minutes,
                        one = R.string.booking_duration_minute
                    )
                )
            }
        }.trim()
    }

This gives the same results, and the tests are green.

But please feel free to ignore the suggestion if you prefer the other version 🙂

val totalSeconds = seconds
val dayInSeconds = Duration.ofDays(1).toSeconds()
val hourInSeconds = Duration.ofHours(1).toSeconds()
val minuteInSeconds = Duration.ofMinutes(1).toSeconds()

totalSeconds >= dayInSeconds -> {
val days = (totalSeconds / dayInSeconds).toInt()
val hours = ((totalSeconds % dayInSeconds) / hourInSeconds).toInt()
val minutes = ((totalSeconds % hourInSeconds) / minuteInSeconds).toInt()

np, we can probably use buildString here instead of a mutableListOf<String>, for example for this first formatting logic:

                buildString {
                    append(
                        resourceProvider.getQuantityString(
                            quantity = days,
                            default = R.string.booking_duration_days,
                            one = R.string.booking_duration_day
                        )
                    )
                    if (hours > 0) {
                        append(" ")
                        append(
                            resourceProvider.getQuantityString(
                                quantity = hours,
                                default = R.string.booking_duration_hours,
                                one = R.string.booking_duration_hour

                    }
                    if (minutes > 0) {
                        append(" ")

                            )
                        )
                    }
                }

I'm not sure this is enough for other languages that we support, but from what I've checked, this is how we do plurals here.

For example, that wouldn't work for Polish, but we don't support Polish, so maybe that's fine.

Yes, our plurals support is quite limited, a limitation of Glotpress, this won't work well for Arabic too, but I don't think we have much to do here.

val minutesPart = resourceProvider.getQuantityString(
quantity = minutes,
default = R.string.booking_duration_minutes,
one = R.string.booking_duration_minute
)
"$hoursPart $minutesPart"
}
}

totalSeconds >= minuteInSeconds -> {
val minutes = (totalSeconds / minuteInSeconds).toInt()
resourceProvider.getQuantityString(
quantity = minutes,
default = R.string.booking_duration_minutes,
one = R.string.booking_duration_minute
)
}

else -> {
val seconds = totalSeconds.toInt()
resourceProvider.getQuantityString(
quantity = seconds,
default = R.string.booking_duration_seconds,
one = R.string.booking_duration_second
)
}
}
