Outlook Calendar Show End Time? How to Display It

Yes, Outlook calendar can show end times for events, and you can control exactly how they appear in your calendar grid. By default, Outlook shows only the start time on calendar items, but you can change the setting to display both start and end times for all appointments and meetings.

Formula

The end time of a calendar event is calculated by adding the duration to the start time:

End Time = Start Time + Duration

• Start Time – the time the event begins, in minutes after midnight (e.g., 9:00 AM = 540 minutes).
• Duration – the length of the event in minutes (e.g., 60 minutes for a 1-hour meeting).
• End Time – the time the event finishes, shown as a clock time (e.g., 10:00 AM).

This is the same logic Outlook uses internally when you set a start time and a duration or an end time.

Worked Example

Using the default values from the calculator above:

1. Start time = 0 minutes (midnight, 12:00 AM)
2. Duration = 60 minutes
3. End time = 0 + 60 = 60 minutes after midnight
4. 60 minutes after midnight = 1:00 AM

The calculator shows 1:00 AM as the end time. This matches what Outlook would display if you created an event starting at midnight with a 60-minute duration.

How to Show End Times in Outlook

Outlook’s calendar view normally displays only the start time on each event block. To show the end time as well, you need to change a display setting. The exact steps vary slightly by Outlook version:

Outlook for Windows (Desktop)

1. Go to the Calendar view.
2. Click the View tab on the ribbon.
3. Click View Settings (or Change View > View Settings).
4. In the Advanced View Settings dialog, click Other Settings.
5. Under “Calendar options,� check the box that says “Show end time� (the wording may be “Show end time for appointments� in older versions).
6. Click OK twice to apply.

Outlook for Mac

1. Open the Calendar.
2. On the Organize tab (or the View menu), choose View Settings.
3. Select Other Settings.
4. Check “Show end time�.
5. Click OK.

Outlook on the Web (OWA) and New Outlook

1. In the calendar, click the View settings (gear icon or the “View� dropdown).
2. Look for “Calendar settings� or “Layout.�
3. Toggle the option to “Show end times� (sometimes labeled “Show event end times�).
4. Save changes.

If you don’t see the option, it may be under Calendar > View > Density and spacing or in the Reading pane settings, depending on your version.

What the End Time Display Looks Like

When enabled, each calendar block shows both times, typically like “9:00 AM – 10:00 AM� instead of just “9:00 AM�. This applies to appointments, meetings, and events in your calendar grid.

For all-day events, Outlook usually shows “All day� instead of times, and end times are not displayed for those.

Common Problems and Fixes

• End time not showing even after enabling the setting: Make sure you are in a calendar view that supports time display (like Day, Week, or Work Week). The Month view may not show times at all.
• The setting is grayed out: This can happen if you are in a shared or read-only calendar. Switch to your own calendar or request edit permissions.
• Only start time shows for some events: Check if the event is marked as “Freeâ€� or “Tentativeâ€� – the display setting should still work, but if the event is an all-day event, times are hidden by design.
• Outlook on the web doesn’t have the option: In the new Outlook, the setting might be under View > Calendar settings > Events > Show end times. If you can’t find it, try the classic Outlook on the web.

Why You Might Want to Show End Times

Displaying end times helps you quickly see how long a meeting will last without opening it. It’s especially useful when you have back-to-back meetings or are scheduling across time zones. It also prevents double-booking because you can visually see where one meeting ends and the next begins.

However, some users prefer to hide end times to reduce clutter, especially in a busy calendar with many short events.

Alternatives to Showing End Times

• Use the Reading Pane: Select an event to see its full details, including start and end times, in the reading pane without changing the grid layout.
• Hover over the event: A tooltip shows the start and end times when you hover your mouse over a calendar item.
• Open the event: Double-click to open the appointment window, which always shows both start and end fields.

Frequently Asked Questions

Why doesn’t Outlook show end times by default?

Outlook’s default compact calendar view shows only the start time to keep the grid clean and readable. Microsoft added the option to show end times as a user preference, but it is not enabled by default in most versions.

Can I show end times for only some events?

No, the setting is global – it either shows end times for all timed events in your calendar or none. You cannot selectively show them for individual events.

Does the end time display affect other people viewing my calendar?

No, the display setting is local to your Outlook client. Other people see your calendar according to their own display preferences, not yours.

Will showing end times make my calendar load slower?

No, it’s just a display change and has no impact on performance.

How do I hide end times again?

Follow the same steps you used to enable it and uncheck the “Show end time� box. The change is instant.
