Try the following measures, I put in the table visual to show you the result because, I don't have your calender table. You can try yourself.

Plan  = CALCULATE(COUNTROWS('Plan Table'),
        FILTER(ALL('Plan Table'),SUMX(FILTER('Plan Table',EARLIER('Plan Table'[Taskfinishdate].[Year])<='Plan Table'[Taskfinishdate].[Year]),COUNTROWS('Plan Table'))),
        FILTER(ALL('Plan Table'),SUMX(FILTER('Plan Table',EARLIER('Plan Table'[Taskfinishdate].[MonthNo])<='Plan Table'[Taskfinishdate].[MonthNo]|| EARLIER('Plan Table'[Taskfinishdate])<='Plan Table'[Taskfinishdate]),COUNTROWS('Plan Table'))),
        FILTER(ALL('Plan Table'),'Plan Table'[Taskfinishdate]>=RELATED(Datetable[Startdate]) && 'Plan Table'[Taskfinishdate]<=RELATED(Datetable[Enddate])))

Baseline = CALCULATE(COUNTROWS('Baseline Table'),
        FILTER(ALL('Baseline Table'),SUMX(FILTER('Baseline Table',EARLIER('Baseline Table'[Baseline_Date].[Year])<='Baseline Table'[Baseline_Date].[Year]),COUNTROWS('Plan Table'))),
        FILTER(ALL('Baseline Table'),SUMX(FILTER('Baseline Table',EARLIER('Baseline Table'[Baseline_Date].[MonthNo])<='Baseline Table'[Baseline_Date].[MonthNo] || EARLIER('Baseline Table'[Baseline_Date])<='Baseline Table'[Baseline_Date]),COUNTROWS('Baseline Table'))),
        FILTER(ALL('Baseline Table'),'Baseline Table'[Baseline_Date]>=RELATED(Datetable[Startdate]) && 'Baseline Table'[Baseline_Date]<=RELATED(Datetable[Enddate])))

You need open task or cumulative task. The open task is based on the end date. And we need the task start date. Also Task ID

I need cumulative No.of tasks(Plan & Baseline),during the projects period..
