Calculate this month's target hours, remaining hours, remaining business days and the daily average you need under a flexible work schedule. It deducts annual, half-day and hourly leave against your standard daily hours and removes weekends and public holidays from the business days, so you instantly see whether you're ahead or behind. Everything runs in your browser.

What it is, who it's for, how it works and why you'd use it.
A Flex Work Calculator works out, under a flexible work schedule, how many hours you still need this month, how many business days remain, and the daily average required to hit your target.
It is for office workers on flexible or flextime schedules, and for PMs, developers and designers who track their own monthly hours.
Enter the year, month and your standard daily hours; it builds the monthly target from business days (weekends and public holidays removed), then deducts annual, half-day and hourly leave. Add your hours worked so far and it divides the remaining target by the remaining business days to show the daily average and your surplus or deficit.
It replaces the spreadsheet math people redo every month, finishing in about 30 seconds while accounting for holidays and leave so you know exactly how many hours a day to work.
