If a Filter rows step uses a date condition such as Today but returns rows from yesterday, the most common cause is that the workflow timezone is different from the account timezone.

In this case, the workflow-level timezone takes priority for the filter behavior. That means the Today condition is evaluated using the timezone set inside that workflow.

Open the workflow, click the three vertical dots beside the workflow name, then click Edit Information.

In the Timezone dropdown, review the timezone set for that workflow. If needed, choose the correct timezone and save the change.

If the workflow timezone is set to a region where the day has already changed, the Today filter may return rows for what looks like tomorrow or yesterday from your local perspective.

To review the default timezone for your account, go to your Account page, click your profile picture or icon, and select Manage account.

Then open User Preferences and confirm the timezone there.

This account timezone works as the default for workflows, but a workflow can override it with its own setting.

If the account timezone and workflow timezone are different, the Today filter follows the workflow timezone.

For example, if your account timezone is still on one calendar day but the workflow timezone is already on the next one, the filter will behave according to the workflow timezone.

Replace Today with a specific date and run the workflow again.

If the fixed date works as expected but Today does not, that strongly suggests a timezone mismatch between the workflow setting and the account default.

If the timezone settings are already correct, review the source column and confirm that:

To solve the issue, make sure the workflow timezone matches the day you want the filter to use.

If you want consistent behavior across workflows, also review the account timezone and keep both settings aligned whenever possible.
