Provide support for Custom Calendars AND default Time Intelligence Functions

This is a great idea!

I believe the 4-5-4 is similar to a 4-4-5 accounting calendar. There are some common calendars for running business, so we to request that time calculations can be set to use standard periods such as 4-4-5 and not based on a calendar year.

This is a common problem, very surprised it doesn't have more votes.

Yes!!!! You can't use any of the quick measure time intelligence features with customer calendars, among other pain points. This would save me a few hours a week. Also, there are several custom calendar idea submissions on this board. It might be a good idea for the support team to consolidate them to get a better gauge of the interest in customer calendars.

Support for Custom Calendar such as 4-5-4 so that data can be analyzed for Current and Prior Periods using DAX such as TOTALYTD etc.

It would be great if there was a way to set a custom calendar. Currently all the calendar functions such as YTD, MTD, QTD, etc. function off of a standard calendar. But a large swath of industries work with different fiscal calendars, for example a Q2-Q2 calendar or in retail where fiscal calendars tend to start post February. It would be great if we could define a start / end date for the year and define period start/end dates for months, quarters, etc.

I'm using a custom retail calendar, but once published on powerbi.com the system get the date column as the reference. so when the user are using the Q&A feature and ask for this year sales, the wrong year is returned.
