Time to go

You can use it as a full sentence. Just say, "Time to go!" Use it to gather your things. Use it to tell your kids to get in the car. You can also add it is at the start. It is time to go sounds a bit more certain. If you are in a hurry, just use the short version. It works for one person or a whole group.

Use it when the party is winding down. Use it at the end of a long work meeting. It is perfect when you are at a restaurant and the bill is paid. Use it when you are texting a friend to meet outside. It is the polite way to say "I am leaving now."

Do not use it if you are angry and storming out. That might feel too casual or dismissive. Avoid it during a very sad goodbye, like at an airport. In those cases, I'll miss you is better. Do not use it if you are the host of a party. It might sound like you are kicking your guests out! Unless, of course, they have stayed way too late.

English speakers value punctuality and clear transitions. We don't like awkward silences when leaving. Saying time to go fills that gap. It acts as a verbal signal for everyone to start moving. In the UK and USA, people often stand up while saying it. This is called the "slap the knees and stand" move. It is a classic social cue.

You will hear time to head out or time to hit the road. These are a bit more casual. If you want to be very fast, just say gotta go. If you are being fancy, you might say it is time for my departure. But honestly, time to go is the gold standard. It is friendly, clear, and works everywhere.
