We identify the parliamentary cycles' starting date by the first session day of the National Assembly after the elections similarly to the official database of the Hungarian legislature (http://www.parlament.hu/orszaggyulesi-naplo-elozo-ciklusbeli-adatai, https://library.hungaricana.hu/hu/collection/orszaggyulesi_dokumentumok/). Some electoral cycles (1861, 1910-1918, 1939-1944) were not followed continously by a next one, thus their end date is the final session day of the legislature. The electoral cycle 1922-1926 lasts until 1927, but the election of the new parliament was held in the December of 1926.
