[Columbine]

Actually, am I going mad or is everyone confused over the days of the week in this thread. OP declares in english s/he sometimes goes to school on Sundays, then uses 'doyoobi', I assume as in the romaji for 土曜日. Which is SATURDAY.

Kyle then responds, talking about wednesdays. (水曜日、すいようび、suiyoubi for the beginners）

Evanny then uses 'dyoobi', which is neither correct for 'sunday' OR 'saturday' in Japanese, but I presume you meant the same as the OP. Certainly isn't Wednesday anyway.

Sunday is 日曜日, にちようび nichiyoubi.
