Is the event still on ?

It appears so. I think this happened with the Haloween event as well which lasted like a day longer. Could be because this event is generating so much revenue and people are trying to get their last 10kms before it ends.

If lucky eggs are still on sale, the event has not ended. As of now, the event is still on.

Yes. Just received my second 7-day strike during the event due to the extra hours.

The shop is still selling the discounted lucky eggs.
