You may also consider using only the date functions:

MTD Start = 
CALCULATE (
    COUNT ( 'events-export'[Invitee Email] ),
    FILTER (
        'DateTable',
        'DateTable'[Year] = YEAR ( TODAY () )
            && 'DateTable'[Month] = MONTH ( TODAY () )
            && DAY ( 'DateTable'[Date] ) <= DAY ( TODAY () )
    )
)
