Or, more flexibly, you could write a JXA function which returned May 1 2018 from a variety of strings, including 2018-05-01 and simply today:

(() => {
    'use strict';

    // mmmDyFromInformal :: String -> String
    const mmmDyFromInformal = strDate => {
        const fmtr = $.NSDateFormatter.alloc.init;
        return (
            fmtr.setLocale(
                $.NSLocale.localeWithLocaleIdentifier('en_US_POSIX')
            ),
            fmtr.setDateFormat('MMM d y'),
            fmtr.stringFromDate(
                $.NSDate.dateWithNaturalLanguageString(strDate)
            ).js
        );
    };

    return [
        mmmDyFromInformal('today'),
        mmmDyFromInformal('2018-05-01'),
    ].join('\n');
})();
