Zohran Mamdani’s mayoral term length follows the standard NYC municipal cycle: a four-year term beginning with his inauguration in early January after the 2025 election, assuming his term timelines align with prior NYC practice. Key points:

• In New York City, mayoral terms are four years long. Mamdani won the 2025 mayoral election and is expected to be sworn in in early January 2026, with the term running through the end of 2029, barring any unusual circumstances. [source conventions: general NYC mayoral term structure; typical inauguration timing]
• The specific dates can be confirmed by official announcements from the City of New York or Mamdani’s campaign/transition team, which commonly set the swearing-in date for January 1 following the November election. [source conventions: typical inaugural schedules]
