printf, translation function and date_i18n adds extra characters

So I am trying to make these strings translatable and in proper PHP/WP format. This works:

'Du ' . date_i18n( 'j M', strtotime( $date_debut->format('j M Y') ) ) . ' au ' . date_i18n( get_option( 'date_format' ), strtotime( $date_fin->format('j M Y') ) );

The equivalent using printf should be something like this:

printf(
            __( 'Du %1$s au %2$s', 'my-plugin' ),
            date_i18n( 'j M', strtotime( $date_debut->format('j M Y') ) ),
            date_i18n( get_option( 'date_format' ), strtotime( $date_fin->format('j M Y') ) )
    );

But for some reason the Year comes out as either 201914 or 201920.

Why are there extra characters on the dates?

EDIT

The results are fine and as expected when using without the printf() function

__('Du ' . date_i18n( 'j M', strtotime( $date_de_debut ) ) . ' au ' . date_i18n( get_option( 'date_format' ), strtotime( $date_de_fin ) ) );

• 1 What’s the result of __() function for this string? Could you var_dump it? – Krzysiek Dróżdż Commented May 18, 2019 at 7:54

Because the translate function __() worked fine, I suspected printf() was the culprit.

Turns out sprintf() is what I needed! printf() arguments work differently
