TARGET2/T2 settlement calendar — the SEPA banking calendar, to predict when a euro transfer settles. TARGET is closed on weekends + six fixed days (New Year, Good Friday, Easter Monday, 1 May, 25 & 26 Dec). ?year= lists the closing days; ?date= says whether it settles (and the next open day); ?date=&addBusinessDays=N returns the value date N settlement days away. The SEPA counterpart of /v1/business-days.
