How to use WITH in a better way to parametrise a date

I love to use CTEs to create nice and clear queries. However, I'm pretty sure the query I created is really inefficient.

Is there a better way to do this and keep things clear ?

with first_date as (    -- selecting just 1 date     --    namely:  1 full year ago    select (extract(year from current_date - interval '1 year')||'-01-01' )::date as date    ), last_date as (    select date from star.dim_date where current_cal_day='Current'), total_active_customers_ps_day as(  select        dd.date        , dd.is_first_day_in_month        , dd.is_last_day_in_month           , count(dc.id) as total_customers    from first_date, last_date,        star.dim_date dd        -- join with dim_client, using first_subscription_start_date & last_subscription_end_date        --   to get the ids of just the active clients         join star.dim_client dc on dd.date             between dc.first_subscription_start_date and coalesce(dc.last_subscription_end_date::date, '3000-01-01')             and dc.created <= dd.date            and dc.first_subscription_start_date >= dc.created::date    where         dd.date >= first_date.date        and dd.date <= last_date.date    group by         dd.date        , dd.is_first_day_in_month         , dd.is_last_day_in_month   )select * from total_active_customers_ps_day ;

I think I'm causing some cartesian joins, since this query is far more efficient

with total_active_customers_ps_day as(  select        dd.date        , dd.is_first_day_in_month        , dd.is_last_day_in_month           , count(dc.id) as total_customers    from         star.dim_date dd        -- join with dim_client, using first_subscription_start_date & last_subscription_end_date        --   to get the ids of just the active clients         join star.dim_client dc on dd.date             between dc.first_subscription_start_date and coalesce(dc.last_subscription_end_date::date, '3000-01-01')             and dc.created <= dd.date            and dc.first_subscription_start_date >= dc.created::date    where         dd.date >=  (extract(year from current_date - interval '1 year')||'-01-01' )::date        and dd.date <= (select date from star.dim_date where current_cal_day='Current')    group by         dd.date        , dd.is_first_day_in_month         , dd.is_last_day_in_month   )select * from total_active_customers_ps_day ;

What's the better way to do this?
