Well, guess nothing is easier than this. But it's a good way to get started! Be aware that the time is NOT the client's local time -- it's the time of the server.
Current time is <%=Time%><br /> Date is <%=Date%><br /> Tomorrow is <%=Date + 1%><br /> Today is <%=WeekdayName(Weekday(Date))%><br /> Tomorrow is <%=WeekdayName(Weekday(Date+1))%>
Current time is 1:32:30 AM
Date is 12/12/2018
Tomorrow is 12/13/2018
Today is Wednesday
Tomorrow is Thursday
