Most of the advice in the other guides comes back to one thing: write when she is awake and not at work. That needs two facts, what time it is in Thailand and what her day looks like. This page is where both live, and the other guides link here rather than repeat the sums.
Thailand is on Indochina Time, seven hours ahead of UTC (written UTC+7), and it does not change its clocks. There is no summer time in Thailand. What changes, twice a year, is your clock. That is why the gap to the UK is seven hours in winter and six in summer, and why a message that reached her at a good moment in March can land at a bad one in April without you doing anything different.
Every time on this page is labelled. "Thai time" means the clock on her phone in Pattaya.
The right-hand column is the one that matters. It says what time it is where you are when it is 3pm in Pattaya, which is the middle of the best part of her day.
| Where you are | Your clock against Thai time | When it is 3pm Thai time |
|---|---|---|
| London, Dublin (winter, GMT) | 7 hours behind | 8am |
| London, Dublin (summer, BST) | 6 hours behind | 9am |
| Berlin, Paris, Amsterdam, Stockholm (winter, CET) | 6 hours behind | 9am |
| Berlin, Paris, Amsterdam, Stockholm (summer, CEST) | 5 hours behind | 10am |
| Dubai (no summer time) | 3 hours behind | noon |
| New York, Toronto (winter, EST) | 12 hours behind | 3am |
| New York, Toronto (summer, EDT) | 11 hours behind | 4am |
| Chicago (winter, CST) | 13 hours behind | 2am |
| Chicago (summer, CDT) | 12 hours behind | 3am |
| Los Angeles, Vancouver (winter, PST) | 15 hours behind | midnight |
| Los Angeles, Vancouver (summer, PDT) | 14 hours behind | 1am |
| Perth, Singapore (no summer time) | 1 hour ahead | 4pm |
| Tokyo, Seoul (no summer time) | 2 hours ahead | 5pm |
| Sydney, Melbourne (winter, AEST) | 3 hours ahead | 6pm |
| Sydney, Melbourne (summer, AEDT) | 4 hours ahead | 7pm |
| Auckland (winter, NZST) | 5 hours ahead | 8pm |
| Auckland (summer, NZDT) | 6 hours ahead | 9pm |
"Summer" means your own daylight saving period. In Europe and North America that is roughly late March to late October or early November. In Australia and New Zealand it runs the other way, roughly October to early April, so a Sydney reader's "summer" row is the one to use at Christmas.
This part is a pattern, not a timetable, and every woman is different. What the women on this site tell us, and what the reply times across many conversations show, is broadly this:
So the window to aim for is roughly 1pm to 6pm Thai time (UTC+7). A message that arrives then is read then. A message that arrives at 4am Thai time is not a problem, it just waits for her lunchtime.
When you make a plan across a time difference, write the time in both zones, every time. "I'll call at 8pm my time, 2am your time" is how you find out it is a bad idea before she does. "Saturday at 3pm Thai time, which is 9am for me" is a plan nobody can misread, even after translation. Dates cross midnight too: Monday evening in New York is already Tuesday morning in Pattaya.
On this site, Tonight shows the time in Pattaya at the top and marks which bars are open now, so you can see at a glance whether she is likely to be at work. The table above is for everything else: a call, a birthday, a flight time.
Thailand is UTC+7 all year. Aim for her afternoon, roughly 1pm to 6pm Thai time. From Europe that is your morning; from the US East Coast it is before bed or first thing; from the West Coast it is your late evening; from eastern Australia it is after work. If a reply takes until her next afternoon, the clock is usually the reason.
