# How to get the number of the day (1 up to 7) as a number instead of a string

### What I’m trying to do

I am trying to retrieve the number of the day in the week from the title of my daily page (YYYY-MM-DD) using this:

``````<% moment(tp.file.title).format("d")
``````

The result is that a Sunday is returned as zero, where I’d like it to be a 7.
To resolve the numbering, I think something needs to be used like (in pseudo code):

correct number = <% moment(tp.file.title).format(“d”)%> +7 - <% moment(tp.file.title).format(“d”)%>

So that Monday is 1, up to Sunday is 7.

### Things I have tried

``````<% moment(tp.file.title).format("d")+7-moment(tp.file.title).format("d")%>
``````

Which created 16 for monday, 25 for tuesday, 34 for wednesday, 43 for thursday, 51 for friday, 61 for saturday, 7 for sunday

You need to convert the textual weekday into a number, and then do the math.

Here is one option for doing this:

``````<%* wd = parseInt(moment(tp.file.title).format("d")); tR += wd == 0 ? 7 : wd %>
``````

Here we convert it to a number and store it in `wd`. Then we append to the output using `tR += `, and the text we append is depending on whether `wd == 0` in case we return 7, or else we return the `wd` itself.
