How can I do this in one query? I want to generate a results set like

today   0
30-day  5
60-day  18

I would like to extract this in a single statement. I'm currently doing it in 3 queries like this:

mysql> select count(me_id) from messages where to_days(me_date)>to_days(now())-7;
+--------------+
| count(me_id) |
+--------------+
|            1 |
+--------------+
1 row in set (0.00 sec)

mysql> select count(me_id) from messages where to_days(me_date)>to_days(now())-30;
+--------------+
| count(me_id) |
+--------------+
|            5 |
+--------------+
1 row in set (0.00 sec)

mysql> select count(me_id) from messages where to_days(me_date)>to_days(now())-60;
+--------------+
| count(me_id) |
+--------------+
|           18 |
+--------------+
1 row in set (0.00 sec)
