# Day Of Week By Name For A Date
|
|
|
|
In [Day Of Week For A Date](day-of-week-for-a-date.md), I explained how to
|
|
determine what day of the week a date is as an integer with PostgreSQL. This
|
|
used the `date_part()` function. By using the `to_char()` function with a
|
|
date or timestamp, we can determine the day of the week by name (e.g.
|
|
Monday). For instance, to determine what day today is, try a statement like
|
|
the following:
|
|
|
|
```sql
|
|
> select to_char(now(), 'Day');
|
|
to_char
|
|
-----------
|
|
Sunday
|
|
```
|
|
|
|
The `Day` part of the second argument is just one of many template patterns
|
|
that can be used for formatting dates and times.
|
|
|
|
See [Data Type Formatting
|
|
Functions](http://www.postgresql.org/docs/current/static/functions-formatting.html)
|
|
in the Postgres docs for more details.
