Leave Calculator - Olchiki Numerals

What does the leave calculator compute?

The leave calculator counts working days between two dates, excluding weekends and public holidays. It helps you plan and track annual leave, sick days, and other time off. For example, if you request leave from Monday October 6 through Friday October 10, and October 8 is a public holiday in your country, the calculator shows 4 working days of leave used, not 5. This gives you an accurate picture of how many leave days a request will actually consume from your balance.

Can I customise the public holidays for my country?

Yes. The calculator comes with preset holiday calendars for multiple countries including India, the United States, the United Kingdom, Australia, Canada, and others. You can also add custom holidays for your region, company, or religious observance that are not in the preset list. Custom holidays are saved locally in your browser so they persist across sessions.

How does the calculator handle half-day leave or partial leave?

The calculator counts full working days. For half-day leave, enter the start and end dates of the half-day period and divide the resulting day count by two. For recurring half-day patterns (e.g., every Friday afternoon), count the number of Fridays in your date range and add them as half-days to your total. The weekly summary view shows you the breakdown of full days and half-days so you can see at a glance how much leave you have used.

How do I calculate leave balance remaining?

Enter your total annual leave entitlement and the calculator tracks how many days you have used versus how many remain. The leave balance tracker shows used days, remaining days, and projects whether you will exhaust your balance before year-end based on your current usage rate. This helps you plan time off without running out of leave unexpectedly.

Does the calculator account for different weekend conventions?

Yes. Most countries use Saturday-Sunday weekends, but several Middle Eastern countries use Friday-Saturday, and some use Thursday-Friday. The calculator lets you select which days of the week count as weekends, so the working-day calculation is correct regardless of your location. This is particularly important for multinational teams where colleagues in different countries have different weekend days.

Can I plan leave around upcoming public holidays to maximise my time off?

Yes. The calculator shows public holidays within your selected date range, so you can see which holidays fall near your requested leave. By strategically booking leave adjacent to public holidays or weekends, you can extend your time off while using fewer leave days. For example, if a public holiday falls on a Tuesday, booking Monday as leave gives you 4 consecutive days off (Saturday through Tuesday) while using only 1 leave day.

How do I use the sick leave calculator?

Enter the start and end dates of your sick leave. The calculator counts the working days between those dates, excluding weekends and any public holidays that fall within the range. For example, if you are sick from Wednesday through Friday and there are no holidays, the calculator shows 3 sick days used. This helps you track how many sick days you have consumed from your annual entitlement.

How do I use the leave calculator to plan time off?

Enter your requested leave start and end dates. The calculator counts the working days between them, excluding weekends and public holidays for your selected country. For example, requesting leave from Monday to Friday gives 5 working days, but if Wednesday is a public holiday, only 4 leave days are consumed. This shows exactly how many leave days a request will use from your balance.

Why was Ol Chiki created when other Indian languages already had scripts?

Santali is an Austroasiatic (Munda) language, unrelated to the Indo-Aryan and Dravidian languages that dominate India. Before Ol Chiki, Santali speakers used the Latin script, Devanagari, or Bengali script — none of which matched the sounds of Santali well. Pandit Raghunath Murmu designed Ol Chiki specifically for Santali phonology, with 30 letters and 5 diacritics that represent every sound in the language. It is one of the few scripts in the world that was intentionally designed rather than evolving organically.
