Leap seconds are always applied at the end of the UTC day of the
last day of the month specified. So the next one will occur on July 1
for most of the people in the world and early evening of June 30 for
those of us in the USA.

When leap seconds are calculated and formally announced is sort
of arbitrary and erratic, not unlike how the earth itself rotates. It's
not a problem really. No software should care or depend on some
precise date of announcement.
