Dynamic Periods for Fiscal Year

Hello all, 

I am creating a Period Table as shown on Chris Webb's blog: Chris Webb's BI Blog: Creating Current Day, Week, Month And Year Reports In Power BI Using Bidirectional Cross-Filtering And M (crossjoin.co.uk)

with the extra bit to add the financial calendar from here: Create Dynamic Periods for Fiscal or Calendar Dates in Power BI - FourMoo | Power BI | Data Analytics

The problem is that my financial months don't always start on the same day of the month and the length of the month is either 28 days (4 weeks) or 35 days (5 weeks). 

In my calendar table, I have the following:

Fist_day_in_year / Last_day_in_year

Fist_day_in_quarter / Last_day_in_quarter

First_day_in_month / Last_day_in_month

First_day_in_week / Last_day_in_week

Is there a way to create Current Month To Date/Current Quarter To Date/Current Year To Date/Rolling Month/Rolling Quarter/Rolling Year using Chris Webb's method? 

Thank you!
