Harvest Moon: A wonderful life Questions

How do you get Tartan? I think it has something to do with going into Takakura's house between 5-10 o'clock(don't know if it's AM or PM, 'cause the site I saw it on didn't say) or something. Does it have to be in a ceartin year, a ceartin time, a ceartin day? I have tried getting Tartan countless times and it won't work! Here are my stats in case you need them...
