 DATE formula: Used to create a date by specifying the year, month, and day.
 EOMONTH formula: Calculates the last day of the month for a given date.
 WEEKDAY formula: Determines the day of the week for a given date.
 NETWORKDAYS formula: Calculates the number of working days between two dates, excluding weekends and specified holidays.
 WORKDAY formula: Returns a date that is a specified number of working days before or after a given date, excluding weekends and specified holidays.
2. How can I calculate the number of days between two dates using calendar formulas? 

Ans. To calculate the number of days between two dates using calendar formulas, you can use the DATEDIF formula. The syntax for this formula is DATEDIF(start_date, end_date, "d"). For example, if you want to calculate the number of days between January 1, 2022, and February 15, 2022, the formula would be DATEDIF(A1, B1, "d"), where A1 contains January 1, 2022, and B1 contains February 15, 2022.
3. How can I automatically highlight weekends in a calendar using spreadsheet formulas? 

Ans. To automatically highlight weekends in a calendar using spreadsheet formulas, you can use the WEEKDAY formula combined with conditional formatting. For example, if you want to highlight weekends in a range of cells, you can apply conditional formatting with the formula =WEEKDAY(A1,1)>5, where A1 is the first cell in the range. This formula checks if the day of the week for the date in A1 is greater than 5 (Saturday or Sunday), and if true, applies the specified formatting.
4. Can I create a dynamic calendar in a spreadsheet using formulas? 

Ans. Yes, you can create a dynamic calendar in a spreadsheet using formulas. One way to do this is by using the DATE formula in combination with other functions like IF, ROW, and COLUMN. By using these formulas, you can generate a calendar that automatically adjusts based on the selected month and year. For example, you can use the ROW and COLUMN functions to populate cells with the corresponding dates based on the selected month and year.
5. How can I calculate the number of weekdays in a month using spreadsheet formulas? 

Ans. To calculate the number of weekdays in a month using spreadsheet formulas, you can use the NETWORKDAYS formula. The syntax for this formula is NETWORKDAYS(start_date, end_date, [holidays]). For example, if you want to calculate the number of weekdays in January 2022, the formula would be NETWORKDAYS("01/01/2022", "01/31/2022"). This formula automatically excludes weekends (Saturday and Sunday) and can also exclude specified holidays if provided in the [holidays] argument.
