Months and seasons

Bangladesh has six seasons!

The rainy season

In the monsoon, heavy rain falls almost every day. The monsoon is a season. Seasons come round every year.

Twelve months

A year has 12 months. January is the first; December is the last. Some months have 30 days, some 31, and February has 28 or 29.

Six seasons of Bangladesh

The Bangla calendar has six seasons (ritu). Each season is about 2 months long. 6 seasons × 2 months = 12 months.

Special days

Pohela Boishakh, the Bangla New Year, is in April. Victory Day is in December. Which month is your birthday in?

Decades and centuries

10 years make a decade. 100 years make a century. Bangladesh became independent in 1971 – more than 5 decades ago. Seconds, minutes, hours, days, weeks, months, years, decades, centuries: from shortest to longest!
