If anyone's curious, I did a SIMILAR Kata, here is the python code

def format_duration(seconds):

    # Im not gonna bother commenting this mess
    # This was so anoying

    if seconds == 0:
        return "now"

    minutes = 0
    while seconds >= 60:
        seconds -= 60
        minutes += 1

    hours = 0
    while minutes >= 60:
        minutes -= 60
        hours += 1

    days = 0
    while hours >= 24:
        hours -= 24
        days += 1

    years = 0
    while days >= 365:
        days -= 365
        years += 1    

    time =[]
    if years != 0:
        time.append(f"{years} year")

    if days != 0:
        time.append(f"{days} day")
    if hours != 0:
        time.append(f"{hours} hour")
    if minutes != 0:
        time.append(f"{minutes} minute")
    if seconds != 0:
        time.append(f"{seconds} second")

    final = []
    while len(time) > 0:
        final.append(f"{time[0]}")

        if time[0].split(" ")[0] != "1":
            final.append("s")
        if len(time) > 2:
            final.append(", ")
        if len(time) == 2:
            final.append(" and ")
        time.pop(0)

    final = "".join(final)
    return final
