How we verified this.

We verified these dates against agenda.parisjetaime.com, the event's own site. The organiser confirms nothing on this page — checking their site against our record is our own act, and we only publish an event once that check passes.

Our crowd forecast is an informed estimate, not a guarantee — check with the organiser and/or local authorities before you plan around it.

our forecast marks a number we worked out from published data; advice marks something we think. Never the other way round.

Named places appear here only after checking their own website; anything unverifiable is left out.
