Count Up Timer to Create an Online Counter From a Past Event

Count Up Timer Sign

Simply enter the date and time of a past event and the count up timer will generate a timer that will begin counting up from the event's date and time.

And not only will the calculator count up the time in years, months, days, hours, minutes, and seconds, but it will also give the total time stated in each of those time units.

Plus, if the past event resulted in periodic savings or earnings (like the savings from quitting smoking or the earnings from working on billable projects), the count up timer will even count the money you have saved or earned since the start date and time. Super cool!

Note that if you would like to count down to future date and time, please visit the Count Down Calculator.

What's Your Important Past Event?

Here are just a few ideas for using the count up timer to count up from a special occasion or event:

  • How long since my last drink (a.k.a., sobriety calculator)?
  • How long since I quit smoking, and how much money have I saved?
  • How long have I been clean (a.k.a., clean-time calculator)?
  • How long since we first met?
  • How long have we been dating?
  • How long have we been married?
  • How long have I been working on this billable project, and how much have I earned?

If you find other uses for the Count Up Timer, please use the feedback form beneath the calculator to let me know.

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

Event date and time:

Select the month and day and enter the 4-digit year for the date you wish to create an event timer for. If the event has a time associated with it, select the appropriate hour, minute, and second. If no particular time is associated with the event you can set the time to whatever time makes the most sense to you. Tap the Now button to set the date and time fields to reflect the current date and time.

Optional: Amount I am saving/earning per time period:

If applicable, enter an amount of money you are saving or earning as a result of the event. Then select the time period the amount is applicable to. For example, if quitting smoking is saving you $8.00 per day, enter 8 in the text field and select day from the drop-down menu. Or, if working on a billable project where you are charging $25 per hour, enter 25 and select hour.

If you would like to save the current entries and results to the device you are using, tap or click on the Data tab and then tap or click on the Save button. If you upgrade your Basic, Local Storage subscription to the Cloud Storage acess level, you can save multiple sets of entries for this calculator to the secure online database, which makes them accessable from any device.

Help and Tools

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
