furious: my sister planned a birthday party for our mother on a day and time in which it will create a huge hardship on me. She knew my schedule when she made the plan.

My mother will be 85 in a few days. My sister planned a surprise party knowing the day, hour and location would be very difficult for me to attend.

That not good. Maybe she will understand if you just can't make it.
