Hello,
Thanks for reaching out!
I would recommend using the tribe_events shortcode and setting the date parameter to a time before your first event. This will show all events from that date, past and upcoming, but the oldest will be first. If you wanted to flip the order, you would need to do a bit of a customization – I would recommend taking a look at this snippet as a starting point.
We are limited in the amount of support that we can provide for customizations, but if you get stuck or have any questions, please let me know – I’ll be happy to try to point you in the right direction!
Thanks,
Jennifer
