I want to create the following button until tomorrow

I managed to create this with only css and html

and here is my code.
.date {
color: #7ed2f6;
font-size: 40px;
font-weight: bold;
}
.save {
color: white;
font-size: 40px;
font-weight: bold;
}
.pill-button {
border: 0.2em solid white;
color: white;
padding: 10px 20px;
text-align: center;
display: inline-block;
margin: 4px 2px;
cursor: pointer;
border-radius: 60px;
}
.right {
display: inline-block;
width: 4em;
height: 4em;
border: 0.3em solid white;
border-radius: 50%;
margin-left: 1.5em;
}
.right:after {
content: '';
display: inline-block;
margin-top: 1.05em;
margin-left: -0.6em;
width: 1.2em;
height: 1.2em;
border-top: 0.3em solid white;
border-right: 0.3em solid white;
-moz-transform: rotate(45deg);
-webkit-transform: rotate(45deg);
transform: rotate(45deg);
}
.greyline {
border-left: 2px solid #8d9ab1;
height: 81px;
display: inline-block;
}
<a href="#" class="pill-button">
<span class="save">Save The Date</span>
<div class="greyline"></div>
<span class="date">Σάββατο 19/9/2020 16:30-17:30</span>
<span class="right"></span>
</a>
