localizetion of digit

what is the filter tag to localize of Archives Calendar Widget’s date digit.

i have tried

add_filter( 'date_i18n', 'make_bangla_number' );
	add_filter( 'number_format_i18n', 'make_bangla_number' );
	add_filter( 'get_calendar', 'make_bangla_number' );

but none of this worked.

so what would be filtered ?
