Dating Rules Calculator (3 Month Rule, 3-6-9, 7-7-7)

See where you are on 3-6-9, the 3 month rule, 3-3-3 and 7-7-7, from one date.

Quick answer

Dating rules like 3-6-9, the 3 month rule and 3-3-3 are checkpoints for a new relationship; 7-7-7 and 2-2-2 are rhythms for making time together. None of them come from research. Enter the day you started seeing each other above: the calculator shows your day count, where you are on each rule, the dates of your 3, 6 and 9 month marks, when the next 7-7-7 date is due, and three questions to ask right now.

Enter the day you started seeing each other and the calculator applies every popular dating rule to your own dates: which stage of the 3-6-9 rule you are in, the day of your 3 month mark, where you are on 3-3-3, and when the next 7-7-7 date is due. Each rule comes with a plain explanation, an honest note that it is not science, and three questions to ask right now.

Checkpoint rules help you decide if a new relationship is right. Rhythm rules help a couple keep making time for each other. Neither kind comes from research, and the people who study relationships say so. The Gottman Institute's own blog, for example, calls 7-7-7 a viral meme.

Which 3 month rule?

You meanWhat it says
3 month rule while datingGive a new relationship about three months before deciding if it has a future.
3 month rule after a breakupWait about three months after a breakup before dating someone new.

The calculator does both: pick Dating someone or After a breakup at the top.

How does the calculator work?

  1. Pick your start date. Your first date, or the day you started talking. Count from whatever feels right to you.
  2. Add how many dates you have had. The 3 date and 3-3-3 rules count dates, not days.
  3. Read your timeline. Day count, your 3 week, 1, 3, 6 and 9 month and 1 year dates, and today marked between them.
  4. Open any rule. Each card says where you are, what the rule claims, and gives three questions that fit this point, with a copy button.
  5. Save the dates. Add the milestones to your calendar or send the timeline to the person you are seeing.

Do these rules actually work?

Not as rules. Nobody has shown that relationships change at month 3, 6 or 9, or that a date every 7 days keeps couples together. What they are good for is a nudge: a reason to check in with yourself at month 3, or to put a date in the calendar this week. Use them that way and ignore the deadlines.

FAQ

What is the 3 month rule in dating?

The 3 month rule says to give a new relationship about three months before you decide if it has a future, or before big steps like meeting family. Around then the early rush settles and you see more of the real person. It is advice, not science, and you never have to wait three months if something feels wrong.

What is the 3 month rule after a breakup?

The other meaning of the 3 month rule: wait about three months after a breakup before dating someone new, so you date because you are ready, not to fill a gap. Pick After a breakup in the calculator to see your 3 month date and three questions to ask yourself first.

What is the 3-6-9 rule in a relationship?

It splits the first nine months into three stages: months 0 to 3 are the honeymoon, months 3 to 6 bring the first real disagreements and habits, and months 6 to 9 are for deciding if it is long term. It went viral on TikTok; there is no study behind those exact months.

What is the 7-7-7 rule?

A date every 7 days, a night away every 7 weeks and a trip every 7 months. It is often credited to the Gottman Institute, but the Institute's own blog calls it a viral social media meme and says the quality of daily connection matters more than the schedule.

What are the 3-3-3 and 2-2-2 rules?

3-3-3 is a set of checkpoints: after 3 dates, 3 weeks and 3 months, ask yourself if this is still worth your time. 2-2-2 is a gentler rhythm than 7-7-7: a date every 2 weeks, a weekend away every 2 months and a bigger trip every 2 years.

What is the 3 date rule?

An old TV trope that the third date is when things get physical. Nobody has to follow it. The right time is when you both want to, and either of you can say not yet on any date.

What is the 3-5-7 rule in a relationship?

We could not find a consistent meaning for a 3-5-7 dating rule; searches for it return trading and decorating rules. People who search it usually mean the 3-6-9 rule, which the calculator covers.

Who pays on a first date?

There is no rule that holds everywhere. A simple approach: whoever asked offers to pay, and the other offers to split or to get the next one. If you are not sure, talk about it lightly before the bill comes.

Can I get reminders for my milestones?

Yes. Tap Add milestones to calendar and the tool makes a calendar file with your upcoming 3 week, 3, 6 and 9 month and 1 year dates, each with questions to ask. It is made in your browser and works with Apple, Google and Outlook calendars.
