Some facts#
- We may think, that adding or subtracting a few days (months, years) to (from) given date is a piece of cake. However, if we go deeper, we will find that there are many potential problems related to days arithmetic. Some months have 30, but other 31 days. Hey, but February has only 28 days! But, wait... once every four years February has 29 days. But which years are leap and which years are not? Argh! Maybe it will be easier to use Calculla?
What is the meaning of each calculator field ?#
- Start date - it is date used as reference to all further calculations. For example, if you want to know what date will be 50 days after Easter set this field to Easter day and number of days to 50.
- Number of days/months/years to add/subtract - this is a number of days (months, years), which will be added (and subtracted) from your reference date set in "start date" field.
- Don't include (Saturdays/Sundays/public holidays) - use this fields to exclude selected days from calculations. For example you can use this option if you want to count next 20 working days from today. In this case you should exclude all non-working days i.e.: Saturdays, Sundays and public holidays. This option is applied when shifting days only i.e. it doesn't affect result of adding/subtracing months or years.
- Your region - this option is used only, when holidays exclusion is enabled (see "Don't include" field). Based on this field, Calculla will adjust list of known holidays to place where you live.
