Issues with horizontal alignment of date when using minipage - date

Question

I'm trying to create a test for my students. I put the teacher's name, date, start time and duration time on the same line using the minipage environment. I don't know why the date field is not aligned with the other fields. If I write anything other than the date, the text lines up perfectly.
The code I am using in overleaf is:
\documentclass[paper=a4, fontsize=10pt]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{times}
\usepackage[brazil]{babel}
\usepackage{amsmath,amsfonts,amsthm}
\usepackage[utf8]{inputenc}
\usepackage{ae}
\usepackage{times}
\usepackage[american voltages, american currents]{circuitikz}
\ctikzset{bipoles/length=2.5em}
\usepackage{anysize}
\marginsize{2cm}{2cm}{1cm}{1cm}
\usepackage{caption}
%\usepackage{columns}
\begin{document}
\begin{minipage}{0.3\textwidth}
Teacher: Guilherme
\end{minipage}
\begin{minipage}{0.2\textwidth}
Date: 22/06/2022
\end{minipage}
\begin{minipage}{0.15\textwidth}
Start: 19:00
\end{minipage}
\begin{minipage}{0.2\textwidth}
Duration: 120 min
\end{minipage}
\vspace{1.5cm}
\begin{minipage}{0.5\textwidth}
Student:\underline{\hspace{7cm}}
\end{minipage}
\end{document}
The result is:
How could I solve the problem?

Answer 1

You can bottom-align the minipages:
\begin{minipage}[b]{0.3\textwidth}
Teacher: Guilherme
\end{minipage}
\begin{minipage}[b]{0.2\textwidth}
Date: 22/06/2022
\end{minipage}
\begin{minipage}[b]{0.15\textwidth}
Start: 19:00
\end{minipage}
\begin{minipage}[b]{0.2\textwidth}
Duration: 120 min
\end{minipage}
Result:

Answer 2

The reason for the different alignment of the date are the / signs which go a bit below the baseline. You can make sure that all your fields have the same height by adding \strut to them:
\documentclass[paper=a4, fontsize=10pt]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{times}
\usepackage[brazil]{babel}
\usepackage{amsmath,amsfonts,amsthm}
\usepackage[utf8]{inputenc}
\usepackage{ae}
\usepackage{times}
\usepackage[american voltages, american currents]{circuitikz}
\ctikzset{bipoles/length=2.5em}
\usepackage{anysize}
\marginsize{2cm}{2cm}{1cm}{1cm}
\usepackage{caption}
%\usepackage{columns}
\begin{document}
\begin{minipage}{0.3\textwidth}
Teacher: Guilherme\strut
\end{minipage}
\begin{minipage}{0.2\textwidth}
Date: 22/06/2022\strut
\end{minipage}
\begin{minipage}{0.15\textwidth}
Start: 19:00\strut
\end{minipage}
\begin{minipage}{0.2\textwidth}
Duration: 120 min\strut
\end{minipage}
\vspace{1.5cm}
\begin{minipage}{0.5\textwidth}
Student:\underline{\hspace{7cm}}
\end{minipage}
\end{document}
