When is Constitution Day?
In 2026, Constitution Day falls on Sunday, March 15, 2026. It is classified here as a Kazakhstani public holiday.
History of Constitution Day
Kazakhstan's current Constitution Day is March 15, the date on which voters approved a new Constitution in a nationwide referendum in 2026. The new constitutional text entered into force on July 1, 2026, replacing the 1995 Constitution and moving the statutory holiday from its former August 30 date. Current calendars must therefore avoid repeating the pre-July 2026 date as if it still applied.
The constitutional reform changed the institutional framework of the republic and was politically debated before and after the vote. A holiday guide should record the enacted legal outcome without presenting official celebration language as an assessment of the reform. Public bodies can use March 15 for civic programmes about the Constitution, state institutions and citizens' rights, while the date remains a nationwide non-working state holiday under the amended Law on Holidays.
Before July 1, 2026, Constitution Day commemorated the Constitution adopted on August 30, 1995. The March 15 referendum approved a replacement Constitution, and implementing legislation changed the holiday date to the referendum anniversary. Historical calendars should therefore retain August 30 through 2025, while current and future calendars use March 15. For 2026 itself, the law took effect after the March referendum; official current references nevertheless identify March 15 as the annual holiday and no longer list August 30.
How Constitution Day is observed
A nationwide non-working public holiday on March 15 under the law effective from July 1, 2026. Weekend extension rules apply to future occurrences. The definition preserves August 30 for years before 2026 and uses the current March 15 date from 2026 onward.

Constitution programmes
Public institutions may explain the current constitutional framework, citizens' rights and the state bodies created or changed by the 2026 text. The new March date means Kazakhstan's future Constitution Day programmes occur near Nauryz rather than at the end of summer.
Official ceremonies
Government and municipal bodies can hold addresses, exhibitions and civic events focused on the Constitution and the referendum anniversary. The new March date means Kazakhstan's future Constitution Day programmes occur near Nauryz rather than at the end of summer.
Public discussion
Universities, media and civil society may examine constitutional law and the continuing implications of the 2026 institutional reform. The new March date means Kazakhstan's future Constitution Day programmes occur near Nauryz rather than at the end of summer.
Dates and observance rules are checked against the official Kazakhstani legal and official guidance. Lunar dates, annual transfers and employer schedules should be confirmed against official notices.
