What day of the week were you born?
Enter your date of birth and this tool reveals which day of the week you were born on — Monday, Tuesday, and so on — then shares the matching line from the traditional Monday’s Child nursery rhyme for a bit of fun. It works for any date, so you can also check anniversaries, historical events, or future dates.
How it works
The tool reads the date you pick and asks your browser’s built-in calendar for its weekday. Browsers follow the proleptic Gregorian calendar, the same arithmetic every modern computer uses, so the result is exact for any recent date. It then looks up that weekday in the Monday’s Child rhyme and displays the corresponding line.
| Weekday | Monday’s Child line |
|---|---|
| Monday | Fair of face |
| Tuesday | Full of grace |
| Wednesday | Full of woe |
| Thursday | Has far to go |
| Friday | Loving and giving |
| Saturday | Works hard for a living |
| Sunday | Bonny, blithe, good and gay |
Worked example
Someone born on 15 June 1990 finds it was a Friday, so their rhyme line is “Friday’s child is loving and giving.”
The calculation happens entirely on your device, and nothing is uploaded.
What people use this for
The most common reason is pure curiosity — everyone wonders which weekday they were born on and most people have no idea. But the tool is useful for more than birthdays:
- Parents and grandparents sometimes want to know the weekday their children or grandchildren were born, especially if the birth was memorable (“she was born on a Sunday morning”).
- Anniversary checks — enter a wedding or significant date to find out which weekday it originally fell on.
- Historical curiosity — enter a famous date (a moon landing, a historical battle, a royal birth) and see which weekday it was.
- Future planning — enter a future date to see what day of the week it lands on before scheduling an event.
About the Monday’s Child rhyme
Monday’s Child is a traditional English fortune-telling nursery rhyme, appearing in print by the 19th century. It was used to assign personality traits based on the weekday of birth, in the tradition of folk astrology. The rhyme has several variant forms; the one most commonly cited today runs:
Monday’s child is fair of face,
Tuesday’s child is full of grace,
Wednesday’s child is full of woe,
Thursday’s child has far to go,
Friday’s child is loving and giving,
Saturday’s child works hard for a living,
And the child born on the Sabbath day
Is bonny and blithe, good and gay.
There is no scientific evidence that birth weekday predicts personality, but the rhyme remains a widely known piece of cultural folklore and a fun addition to knowing your birth day.
A note on dates before 1582
For modern dates (roughly 1582 onward, when most of Europe began adopting the Gregorian calendar), the tool’s answer matches the calendar that was in use at the time. For dates before that, the tool uses the proleptic Gregorian calendar — mathematically extending today’s calendar backwards — which may differ from the Julian calendar actually in use at the time. For family history research in living memory, the result is always accurate.
