Daily data
Data for the previous day is generally available from 9AM local time for all countries. Consider the timezone difference when working on accounts from different locations. If you're unsure which timezone your account is based on, refer to What timezone is my account?
Weekly data
Every Sunday (visible in the application on the following Monday). Weekly imports on the weekend take longer than normal due to the weekly aggregations, so the usual weekday import times don't apply. This can affect both Saturday and Sunday. If you are trying to pull EMEA data via an API call, you should delay the call to 1700hrs onwards, as data is normally ready between 1400hrs-1700hrs.
Monthly data
First of every month (visible in the application on the 2nd of the month).
