Aimtrust.com administration receives so many questions about their days off, that they were forced to make a separate update concerning this topic and sent it to the members:
We frequently receive questions about calendar of holidays. Please find below a brief explanation about the days-off.
There isn't accruing yields, processing withdrawals and deposits on days off and weekends.
This has been well described in the co-operation agreement, and in the Help Center documents.
We inform about it regularly in the web site's News, too (see https://www.aimtrust.net/aim/news.html).
