How week and day numbers are counted

Knowing the day of the week for historical or future dates is essential for planning, logging events, and scheduling. This tool maps calendar dates directly to weekdays in English and Bengali. It also calculates:

  • Day of Year: The position of the day from January 1st (e.g. January 1 is Day 1, December 31 is Day 365, or 366 in leap years).
  • ISO Week Number: The standard week numbering system where Week 1 is the week containing the first Thursday of the year.
  • Weekend Status: Recognizes if the selected date falls on a weekend (Saturday or Sunday).
Which timezone is used for calculation?
Calculations run locally using your browser's local timezone. The date string from the input (YYYY-MM-DD) is parsed using the local timezone offset to prevent shifting the date backwards or forwards by a day.
What calendar system does this follow?
It follows the standard **Gregorian Calendar** system which is used internationally for civic, commercial, and political scheduling.
