Yes, the events of act one take place in one day.
It depends which act you are talking about.
First speaks Romeo, in Act I. Scene I. Romeo: "Is the day so young?"
Starts on Tuesday, ends on Wednesday.
"The day is hot, and the Capulets are abroad."
In Act 2, Scene 4 of Romeo and Juliet, the Nurse complains about being exhausted from searching for Romeo, dismissing Romeo's playful banter, and teasing Juliet about the upcoming marriage. She also grumbles about the physical toll the day has taken on her.
day symbolizes hatred and fighting because all the fights happen during the day and Romeo and Juliet can't be together during day.
Romeo and Juliet contains dramatic irony. The best example of dramatic irony in the play is in Act 5 when Romeo sees Juliet and thinks that she is dead because of the potion she took earlier that day to make her appear dead. Romeo sees this and then stabs himself and when Juliet wakes up and sees that Romeo has killed himself she then commits suicide also.
In the afternoon. In Act II Scene 4 Romeo says "Bid her devise some means to come to shrift this afternoon; and there she shall at Friar Lawrence's cell be shrived and married."
"The day to cheer and night's dank dew to dry"- Act 2, Scene 3, line 6
In Act III, Scene 2 of Romeo and Juliet, Juliet describes the day as "black and sour" because her beloved Romeo has been banished from Verona. She expresses her sadness and longing for Romeo's presence, finding it difficult to bear his absence.
A good question which you may well be asking about any character in the play except Juliet, the Nurse, Juliet's mother and Romeo's mother. Be more specific and we can talk about what Peter or the Friar or Romeo or Tybalt does all day. This is an important question for anyone who wants to play the part of Peter or the Friar or Romeo or Tybalt.
She will get information about where and when they will be married
