A DateTime extension to show a friendly date based on the value passed in and DateTime.Now

DateTimeExtensions.cs

public static class DateTimeExtensions
{
  public static string ToFriendlyDate(this DateTime date)
  {
    // Calculate the elapsed time
    TimeSpan s = DateTime.UtcNow.Subtract(date);

    // Get total number of days elapsed.
    int dayDiff = (int)s.TotalDays;

    // Get total number of seconds elapsed.
    int secDiff = (int)s.TotalSeconds;

    // If it's the current day...
    if (dayDiff == 0)
    {
      // Less than one minute ago.
      if (secDiff < 60)
      {
        return "just now";
      }

      // Less than 2 minutes ago.
      if (secDiff < 120)
      {
        return "1 minute ago";
      }

      // Less than one hour ago.
      if (secDiff < 3600)
      {
        return string.Format("{0} minutes ago",
          Math.Floor((double)secDiff / 60));
      }

      // Less than 2 hours ago.
      if (secDiff < 7200)
      {
        return "1 hour ago";
      }

      // Less than one day ago.
      if (secDiff < 86400)
      {
        return string.Format("{0} hours ago",
          Math.Floor((double)secDiff / 3600));
      }
    }

    // Everything else...
    if (dayDiff == 1)
    {
      return "yesterday";
    }

    if (dayDiff < 7)
    {
      return string.Format("{0} days ago",
        dayDiff);
    }

    if (dayDiff < 31)
    {
      return string.Format("{0} weeks ago",
        Math.Ceiling((double)dayDiff / 7));
    }

    return date.ToString();
  }
 }

Thanks for sharing. Can you implement multi-language functionality?
