Fix SharePoint Calendar Items Missing from Current Month View
Question details
Fix a SharePoint calendar view issue where events or tasks spanning multiple months do not appear in the current month.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- A user accesses a SharePoint calendar view to track multi-month tasks or events, expecting all active items to load correctly upon opening the page.
- Observed behavior
- Items spanning two months do not display in the current month's default view until the user navigates to the next month and back. Simply recreating the calendar view fails to resolve the rendering issue.
Before proceeding, check your current Calendar View settings to ensure no active date filters or list limitations are unintentionally hiding the multi-month items.
Recreate the SharePoint List from the Existing List
Since the rendering issue is often tied to the original list's data structure, duplicating the list layout and moving the items over provides a permanent fix.
If recreating the view itself doesn't work, the bug is likely rooted in the specific SharePoint list. Creating a new list based on the existing template will give you a fresh structural foundation without the display glitch.
Open your SharePoint Online site, click on the gear icon in the top right corner, and select 'Site Contents'.
Click the 'New' button at the top of the Site Contents page, select 'List', and then choose the 'From existing list' option.
Choose the problematic list as your template, give your new list a name, and click 'Create' to copy the structure.
In your newly created list, create a new Calendar view by clicking on the view options in the top right, selecting 'Create new view', and choosing 'Calendar'.
Manually add or copy your existing tasks and events from the old list into the new list. Your items will now display properly across multiple months.

Frequently Asked Questions
Why do SharePoint calendar items disappear when spanning multiple months?
This is a known rendering bug within certain SharePoint Online lists. The view fails to fetch multi-month event boundaries on the initial page load. Toggling the month forces the page to refresh its queries, displaying the item. Recreating the entire list resolves the underlying bug.
Will creating a list 'from existing list' copy my calendar events automatically?
No. Creating a SharePoint list from an existing list only copies the columns, views, and structural formatting. The actual list items (your data and events) will need to be moved or copied over manually or via Power Automate.
How do I verify if my items are hidden instead of missing due to a glitch?
Go to the list settings for your Calendar view and scroll down to the 'Filter' section. Ensure that no conditions are actively filtering out items based on their Start Date or End Date being outside the current month.
Does this issue happen on the SharePoint desktop app or just SharePoint Online?
This specific rendering issue is primarily observed in the web-based SharePoint Online environment where modern and classic list view web parts handle multi-month data queries inconsistently.
