Read the full account

Sovnarkom decreed that 31 January 1918 would be followed by 14 February 1918, adopting the Gregorian calendar. Lenin chaired the government. Church and old-style dating continued unofficially.

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.

Why it matters

Direct contribution. Medium confidence.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

    Lenin’s Sovnarkom skipped 13 days to align civil time with most of Europe. It is an administrative modernization, not a welfare miracle.

What changed

Fact → Driver → Indicator. Relationship strength orders the paths; it is not the observed indicator movement.

What the sources establish

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

Later commission estimates are attributed to those commissions.

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

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. 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.
