eg this tick stream event shows the 23rd of jan:
https://www.thecrag.com/event/13053085503
The ascent facet shows the correct date:
https://www.thecrag.com/ascents/between/2026-01-17+2026-01-17/by/brendanheywood/?sortby=when-climbed,desc
This either used to say the correct date or it said it was an ascent from the past and showed the date. Either would be ok.
