January 20th 2021 is the day his first term ends. But there's a possibility that he could be re elected into office for another 4 years which would make it Jan 20th 2025 until Donald Trump leaves office for good.
I hope he doesn't get back into office a new better president is elected after his first term. We need Donald Trump out of office.
Until his first term is up we have 3 years, 6 months and 21 days and 14 hours as of this post.
Here's a countdown clock on when Donald Trump's first term ends.
