How do I show availability till midnight?

Hi ​@Ankur, sorry the system isn’t cooperating with you. This is a pretty unique use case and a known limitation with Calendly. We can get you most of the way there, however at this time Calendly does not support events that wrap around from one day to the next. Below I’ve showed you how to set up your schedule to make you available at your suggested times however you will run into problems with scheduling events that run from one day to the next. There are a couple workarounds. One, make shorter events and in the event type description, which the invitee will read, just explain that the event will run past midnight. The other, more risky option, is you could update your timezone so that midnight is at a different time somewhere else in the world. When your invitee goes to schedule with you they will see your Availability in their timezone. But you, as the host, will see it in another. This should allow you to create events that wrap around from one day to the next in your local timezone but all exist on the same day in another timezone. You’ve tricked Calendly into respecting a different 24hour period. Because Calendly auto-detects timezones, based on your connected calendar, there are some potential hiccups you may have to work out. 

You should be able to manually type in 12:00AM and Calendly will recognize that schedule. If your schedule wraps around to the next day I would enter it this way. Your start time availability → 12:00AM and then on the next day 12:00AM → end time. Then that same day your next start time to 12:00AM. You can enter multiple openings within a single day. I’ve updated a schedule to show you what that might look like
