## Key Takeaway:

- Understanding Buddhist and Gregorian calendars: The Buddhist calendar is based on the lunar cycle, while the Gregorian calendar is based on the solar cycle. Both calendars have unique features that are important to understand when converting between them.
- Converting Gregorian calendar to Buddhist calendar: Using Excel formulas makes it easy to convert Gregorian dates to Buddhist dates. Follow the step-by-step guide provided in the article, and use the appropriate Excel formulas to calculate the Buddhist year, month, and day.
- Converting Buddhist calendar to Gregorian calendar: Excel formulas can also be used to convert Buddhist dates to Gregorian dates. Calculating the Gregorian year and month requires similar formulas to the conversion process in the opposite direction. Refer to the article for specific details on how to calculate the Gregorian day from a Buddhist date.

## Understanding Buddhist and Gregorian Calendars

**I’m a data analyst**, and sometimes I have to work with calendar systems from different cultures and regions. So, it’s essential to know the Buddhist and Gregorian calendar systems. Let’s start by exploring the **Buddhist calendar system**. We’ll find out its origin, features, and applications. After that, we’ll look at the **Gregorian calendar system**, which is more widely used. We’ll compare it to the Buddhist calendar. Finally, you’ll understand how to convert between these two calendar systems with Excel.

### Introduction to Buddhist Calendar System and its key features

The **Buddhist calendar** is widely used in countries such as Thailand, Cambodia, and Laos. It is a lunisolar calendar. It is different from the Gregorian calendar, which has fixed months. Buddhists have different month lengths and intercalary months to align lunar cycles with solar years. Here’s a six-step guide for understanding it better-

- This lunar calendar predates the Gregorian calendar by over 500 years. It began in 544 BC with Lord Buddha’s passing.
- It relies on astronomical movements and religious rituals.
- The first month corresponds to April’s full moon or Vesakha Puja, which is Buddha’s birth anniversary.
- Lunar eclipse days are celebrated instead of public holidays.
- Events coincide with specific phases of the moon, e.g. Poya, Navam Poya, and Wesak Poya.
- Each year is associated with an animal sign from the Chinese zodiac –
**Rat/ Ox/ Tiger/ Rabbit/ Dragon/ Snake**etc.

This system is constantly recalibrated with astronomical observations. It is one of Asia’s oldest timekeepers. It also has common terms such as *‘Pakinnaka Vara’* and *‘Thai Solar Calendar.’* To understand the differences between these two systems, look at how they synchronize with the sun and seasons, the seven-day week pattern, the month lengths, and the identification of specific days with religious or historical significance.

### Overview of Gregorian Calendar System and its key features

The **Gregorian calendar** is widely used today. It was introduced by **Pope Gregory XIII** in 1582, as a reform of the Julian calendar. It is a solar calendar, based on Earth’s orbit around the Sun. It measures time in periods of 365 or 366 days.

Unique features of the Gregorian calendar include **leap years**, which occur every four years, and century years divisible by 400 are leap years. Months consist of January to December with varying number of days, and a week is seven days – Sunday, Monday, Tuesday…Saturday.

Due to resistance from Protestant and Orthodox churches, many countries adopted the Gregorian calendar gradually over several centuries. Nowadays, it is accepted globally.

Next, we explore how to convert between the Gregorian and Buddhist calendars. The **Buddhist calendar** is based on lunar cycles, while the Gregorian calendar is based on solar cycles.

## Converting Gregorian Calendar to Buddhist Calendar

Converting the Gregorian calendar to the Buddhist one can be tough. Especially when using Excel formulas to calculate Buddhist year, month and day. But, with the right help, this task is doable! Here, I’ll guide you through step-by-step how to use Excel formulas. We’ll cover all the details, from calculating the Buddhist year to the day. So, let’s get started!

**I’ll show you everything you must know to understand the conversion process without confusion.**

### Step-by-step guide to using Excel formulas to calculate the Buddhist year

**Open Microsoft Excel and create a new workbook**.

In cell A1, put in a **Gregorian date** (e.g. 25/07/2021).

In cell B1, input **=YEAR(BUDDHIST(Gregorian date))**.

Replace “Gregorian date” with the cell reference of your chosen Gregorian date – e.g. A1.

This will give you the corresponding year in the Buddhist calendar.

You can use this formula to easily convert any specific date from the Gregorian calendar to the Buddhist one. It is especially helpful for those who need to work with both formats or for those looking to convert important dates.

Plus, you can use **conditional formatting in Excel** to color-code cells depending on whether they fall on a certain Buddhist holiday or special occasion.

Now let’s learn how to calculate the Buddhist month using Excel formulas!

### How to calculate the Buddhist month using Excel formulas

To calculate the Buddhist month using Excel formulas, here’s what to do:

- Create a table with four columns – Year, Month (Gregorian), Month (Buddhist), and Days in Month (Buddhist). Fill it with true data.
- Use the following formula:
`=IF(DAY(E2)<=15,MONTH(E2)+11,MONTH(E2)+12)`

. In this formula, E2 is the Gregorian date. - The formula checks if the day of the Gregorian date is less than or equal to 15. If so, 11 is added; if not, 12 is added.
- This formula only works for dates after January 1st 1940 CE, since that’s when Thailand adopted the western calendar.
- Copy and paste the formula down each row in the table until all rows are complete.

**Convert dates accurately between these two systems!** Follow these steps in Excel to calculate the Buddhist month without any errors.

### How to calculate the Buddhist day using Excel formulas

To calculate Buddhist dates using Excel formulas, you can follow certain simple steps. Here's a table to guide you:

Task | Formula |
---|---|

Convert Gregorian year to Buddhist year | =(Gregorian Year)+543 |

Calculate Buddhist Era | =IF(ISBLANK(Gregorian Month),"",IF(Gregorian Month<4,"BE "&Buddhist Year,Gregorian Year+544)) |

Determine Year Type | =LEFT(Buddhist Era,2) |

Calculate Offset Value | =VLOOKUP(Year Type,{"BE",0; "sA",-544},2,FALSE) |

Calculate Buddhist Date | IF(ISBLANK(Gregorian Date),"",Gregorian Date+Offset Value) |

To get the correct Buddhist date, start by adding **543** to the Gregorian year. Then, if there's a Gregorian month, calculate the appropriate Buddhist Era. If it's before April, display it as a **BE year plus the Buddhist year**. Otherwise, show the Gregorian year plus **544**.

After that, determine the year type. This will help you calculate the offset value. Finally, create a formula for calculating a specific date in the Buddhism calendar.

**Pro Tip:** Before converting between calendars, double-check all data points for errors.

Next, we'll look into **'Converting Buddhist Calendar to Gregorian Calendar'**.

Next, we'll take you through a step-by-step guide to calculating Gregorian month using Excel formulas.

### Step-by-step guide to calculating the Gregorian month using Excel formulas

Calculate Gregorian months with Excel formulas in 4 steps:

- Convert Buddhist year to Julian day number:

=365*BuddhistYear+(Int(BuddhistYear/4))+(BuddhistDay-1)+1721425

*"BuddhistYear" and "BuddhistDay" are from the Buddhist calendar.* - Calculate days since January 1, 4713 BC:

=JulianDay-2415020.5 - Multiply result by 0.03218101 to get the number of tropical years.
- Use Excel's EOMONTH function to find the end of that month:

=EOMONTH("December 31, " & (PreviousYear+TropicalYears), MonthsToAdd)

**A Step-by-Step Guide to Calculating the Gregorian Month using Excel Formulas:**

Convert Buddhist year to Julian day number.

Then count days since **January 1, 4713 BC**.

Turn that value into tropical year count.

Add it to **December 31st** of the year before desired month to find where it fits along with other months.
