SeaTable formulas offer you several ways to work with the data in your tables. For example, formulas can be used to automatically determine the time between two dates. By entering a corresponding formula, you can thus calculate the duration of a vacation, among other things, and add it to a formula column of your table.
Calculate duration of a vacation
In the concrete example, the goal is to use a formula to calculate the duration of the vacations collected in the table.
To do this, first add a formula column to the table, in whose editor you can then insert the formula.
To calculate the time between two dates, first add the "dateDif" function to the formula, which you can find in the formula editor under the Date functions tab.
In order for the formula to calculate the duration of each vacation, you must refer to the columns where the arrival and departure dates are recorded. It is especially important that the column names are framed with curly brackets.
Finally, you add the calculation methodology to the formula, which decides in which format the duration of your vacations will be displayed afterwards. If you want to calculate the time in days, write a "D" (for days) at the end of the formula. Before confirming, you must close the parenthesis so that the formula is accepted as valid.
After confirming the entered formula, the duration of each vacation will be calculated and automatically displayed in the formula column of your table.
Please note that the formula always calculates a date from/to 00:00, so the departure day is not included. If you want to include the departure day as a lump sum, for example November 8, 9, 10, 11 and 12, you can write "+1" at the end of your formula.
