Niedersachsen Business Day Calculator
Last reviewed: May 19, 2026 · Holiday data: June 24, 2026
Calculate business days in Niedersachsen with its own statewide Feiertage. Niedersachsen shares the Monday to Friday working week and the Saturday and Sunday weekend with the rest of Germany, but its Feiertage calendar is different, so due dates and deadlines can land differently from the count built on the nine nationwide Feiertage.
How Niedersachsen differs from the nationwide German holidays
Lower Saxony, the second-largest German state by area, adds Reformationstag on 31 October as its single statewide Feiertag, in force since 2018. In 2026 it falls on a Saturday and in 2027 on a Sunday, so in both shipped years the Lower Saxon working-day count equals the nationwide German count; a difference appears only when 31 October is a weekday. Lower Saxony does not observe the Catholic holidays of the south such as Fronleichnam or Allerheiligen. The working week is Monday to Friday with a Saturday and Sunday weekend.
Worked example
Adding 2 business days to Thursday, October 29, 2026 using Niedersachsen's Feiertage lands on Monday, November 2, 2026.
