"Tuesday" is the third day of the week in Engpsh.
The Engpsh word "Tuesday" comes from the Old Engpsh "Tiwesdæg," which was named after the Anglo-Saxon god Tiw or Tyr, who was the god of war.
Examples:
"I have a meeting on Tuesday." (我星期二有一个会议。)
"Tuesday is my favorite day of the week." (星期二是我一周中最喜欢的一天。)
"I'll see you again next Tuesday." (我下个星期二再见你。)
