Get single letter abbreviation of week day.

See original GitHub issue

Description of the Issue and Steps to Reproduce:

I need to get single letter abbreviation of week day e.g. R for Thursday, F for Friday, S for Saturday, U for Sunday.

Using moment().format('d') give the number of the day of the week.

Is this supported by moment or can I added explicitly?

Environment:

Chrome 63 on OSX.

Moment version: 2.20.1.

The shortest form you can get is 2-letters (in English): moment().format('dd')

I’ve never seen Thursday abbreviated as ‘R’. Have you made that up?

If you’re not going to use the existing minimal weekday abbreviations used by dd, you can use updateLocale to override

moment.updateLocale('en', { weekdaysMin: 'U_M_T_W_R_F_S'.split('_') });
moment().format('dd');

However… I would strongly advise against doing this. I can’t think of any scenario where a 1-character abbreviated weekday makes sense: it makes no sense on a calendar, as dates are 2-digits, and it makes no sense in isolation where ‘T’ and ‘S’ will be confusing abbreviations unless the full set of other characters is known. And, frankly, U and R are ridiculous stand-ins for Sunday and Thursday in any circumstance (both of which contain a ‘U’…)
