# Sovnarkom adopts the Gregorian calendar

Date: 1918

## The fact

Sovnarkom decreed that 31 January 1918 would be followed by 14 February 1918, adopting the Gregorian calendar. [Lenin](/people/vladimir-lenin) chaired the government. Church and old-style dating continued unofficially.

Later speeches, cult, and measured outcomes are not mixed into this Fact.

## Context

This is an administrative Fact. It does not redeem terror. It does make dated diplomacy with the West less error-prone.

Shared responsibility with other offices is part of the record. Sharing is not a reason to drop this person's documented role, and it is not a reason to treat every later consequence as their handwriting.

## Evidence and sources

The calendar decree is official. Britannica independently records Russia’s 1918 switch.

Official or archival record: Decree on the introduction of the Western European calendar, 24 January 1918 (https://www.marxists.org/history/ussr/government/1918/01/26.htm; Marxists Internet Archive / Sovnarkom reprint). Later commission estimates are attributed to those commissions.

## Significance

Small improving public-administration path. Direct contribution. Medium confidence.

The attached driver is [quality-of-public-administration](/drivers/quality-of-public-administration).

## What is established and what is not

Established: Soviet Russia skipped to 14 February 1918 Gregorian. Not established: that this improved household welfare by itself.

What would change the picture: a contradictory original protocol with a different date or signatory; a demonstrated forgery; or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of war, weather, or unauthorized local action.

The documentary limit is the same for every instrument in this dossier. Central files can show that an order was issued; they cannot reconstruct every locality's implementation. Memoir and literary evidence is independent texture, never the sole causal source. Official statistics of the period are treated as claims with known incentives. Later archival openings and museum publications are independent or successor-state records. They do not convert this Fact into a personality score and do not cancel the original instrument. The contribution is direct where this person signed, chaired, or issued the act, and remains bounded by other offices that had to act. Readers who want the welfare path should open the named driver rather than treating a portrait as the mechanism.
