Hi,
take a look at this example:

I've created a sample table:

create table users(id serial, joining_date date);

and filled it with sample data:

insert into users(joining_date) select now() - (j::text || 'days'
)::interval from generate_series(1,10000) j;

Then the query showing up all users who complete 5 and 10 years this month
can look like:

with u as (
select id, date_trunc('month', age(now()::date, joining_date)) age
from users
)
select *
from u
where u.age in ('5 years', '10 years');
