Determine length of string?

Is there a way to determine the length of a string? For example, sometimes my date string is too long and overflows the width of the watch, and on those days only I want to abbreviate the day name. Is there a way to programmatically determine this, or do I need a lookup table (Wednesdays, Thursdays, and Saturdays in September, Wednesdays in October, etc.).

@ahecht Unfortunately, this isn’t supported right now. Thanks for the input though, we’ll definitely look into it for the future.
