The reason why 2015 has been up to 3 days on Friday 13th

Will you believe that Friday 13th is a bad day, "good little data"?

>>>Why are people "afraid" Friday the 13th

With many people, Friday 13th is a bad day and everyone dodges it. But 2015 "favored" us with 3 "opportunities" to experience this special day and today 13/2 is the first time of the year. The next two special days will be March 13 and November 13.

However, have you ever wondered, how many days a day are on the 13th and how often are they in a year? The following article will help you answer this question.

How many days is a Friday on the 13th?

By math, the researchers calculated that any one year had at least one Friday on the 13th and at most three days. One year has three 6th days on the 13th when and only if the first day of the year is Thursday (for non-profit year) or Sunday (for leap year).

Since the first day of 2015 - January 1, 2015 falls on Thursday, we will have the opportunity to enjoy the 6th time on the 13th day. Because a regular year (not a leap year) has 365 days so when the first day of the "start up" year on Thursday, we will start February, March and November on Sundays - corresponding to these months will be on a Friday 13th.

This event happened in 1998 and we will repeat this a total of 11 times in the twenty-first century - in particular: 2009, 2012, 2015, 2026, 2037, 2043, 2054, 2065, 2071, 2082, 2093 and 2099.

Besides, according to mathematical experts, the distance between the last Friday and the 13th day can only be 27, 90, 181, 244, 272, 335 or 426 days. Therefore, the last two 6th days of the 13th may be more than a year apart. That is the case of August 13, 1999 and October 13, 2000.

Will there ever exist three days of the sixth day of the 13th in a leap year?

According to researchers, this may happen if the leap year begins on Sunday, and these special days are January, April and July.

However, this cycle to be able to happen will be 28 years. Therefore, if you have enjoyed the three days of the 13th and the 13th in January, April and July in 1984, it is not until 2040 that you have the opportunity to experience this "feeling" again.

Friday 13th - a coincidence or is it super luck?

According to Western conception, Friday is the worst day of the week and the 13th is the worst day of the month, so when those two things come together, Friday 13th has created a great fear. .

People even set for the sixth fear syndrome on the 13th, a name, "paraskevidekatriaphobia" , in which "paraskevi" is 6th, "dekatria" is number 13 and "phobia" is fear (according to the Greek language).

However, in fact, there is no written evidence that Friday 13th is considered unlucky before the nineteenth century. The earliest known reference in the UK shows that composer Gioachino Rossini died on Friday 13th.

In the Bible, there is an unfortunate number 13. Judas - Jesus' antagonist is the 13th guest in the "Last Meal". Meanwhile, in the ancient city of Rome, witches often gather into groups of 12, the 13th character is the devil.

Or Adam and Eve were expelled from the paradise garden on Friday, after tasting the Forbidden Fruit and not to mention, the day of Jesus' crucifixion was also the sixth day .

But there are also many cases that have been reported to have been lucky in the day being said to be "unlucky" . As of April 2012, Carolina Furdui in Nampa (USA) won a lottery prize of up to 250,000 USD (about 5.2 billion VND) on Friday 13th fateful day.

Carolina Furdui from Nampa (USA) won the lottery prize on Friday 13th.

American researchers claim that superstition over the centuries has made people a habit of fear. Therefore, instead of sitting trembling or worrying too much about the misfortune that will come on the 6th day of the 13th, try to bring joy to yourself.

Self-confidence and joy will always bring you happiness. And more than welcome a bustling Valentine's Day, a warm Lunar New Year beside those who love.
