Since the introduction of iOS 18, there is a new button in your iPhone calendar :
you can now get a better overview of your week while in your day-view !

To get 2 days (e.g. today and tomorrow) on your screen side-by-side, do this :

• open your Calendar on your iPhone
• when the YEAR calendar view, click on the ‘Today’ button (bottom left)
• when the MONTH calendar view opens, click on the ‘Today’ button (bottom left) – again
• when in the DAY calendar view, click on the odd-shaped button in the top-bar (on the left of the Search / Looking Glass button)
• in the pull-down list that appears, select “Multi Day”
• click outside the pull-down list to close it
• now, you can see 2 days (e.g. today and tomorrow) next to each other and you can scroll through your week using the weekday bar at the top

That’s it !

enjoy 😉
