Frequently Asked Questions
Can it be moved to the beginning of a month or a 1-year period?
Months and years in the calendar have irregular lengths, so they are excluded from this tool. Days are calculated as fixed 24 hours, and the number of days between actual dates is calculated using a date difference calculator.
