Subordinating Conjunctions

As it is a difficult day, I am trying not to stress out.

If you find out, please let me know.

While I was fixing the report, there were many changes with data.

Can I call you after the meeting?

I was about to text you when I received your email.

They waited for our response until 11 o'clock.

I'm staying in although I wish I weren't.

I have changed the document because there were a few mistakes that needed fixing.

That task must be finished before afternoon.

The meeting has been rescheduled since tomorrow is a national holiday.
