Why do I have the letter 'P' after the time?

That’s part of the time formatting. How are you using the shortcode?

This should default to the site’s time format, what do is the time format settings in Settings > General?

This is the current time format on the site:

g:i a T

Timezone: Thunder Bay (EST or UTC -5)

By removing the ‘T’ in the formatting seems to solve the problem, Thanks.

Maybe in the future there will be a time formatting selection/option for the plug-in that does not use the WordPress setting (just in case what works for the rest of the site does not work for your plug-in). I didn’t want the ‘EST’ showing up in the calendar anyway, however is preferred everywhere else.

Thanks for getting back to me on this.

There is a bug then, in that that ‘T’ is not being correctly interpreted. This will hopefully be fixed in 3.0.2

There is an option for over-riding the time format (see timeFormat and axisFormat here: https://docs.wp-event-organiser.com/shortcodes/calendar).

Other date/time formats can be altered either in the templates, shortcode attributes or widget settings.
